  2. Faberge Ermine Trace, BSH ny 09 11 68, the sire of Lorenzo Ermine Trace
  3. Ermine Trace Barkhat, BSH as 09 11 33 68 on PawPeds, the sire of Faberge Ermine Trace

That is 4 recorded parent links, and the animal at the end of it has a laboratory result, so what this cat could carry is not a guess about a line but a consequence of a test on a relative. Every step is a parent recorded in this register from a document; none of them is an assumption. The full genealogy is drawn below, and the sources for each animal are on its own page.

The variant available to this cat

DBE-nad, not established for this animal. A DNA genotype sits 4 generations above this cat. Ermine Trace Nadeya is genotyped DBE-NAD. That does not settle what this cat carries, because a heterozygote passes the variant to half its offspring and the generations between are not tested. It names the variant available to this animal and the one to test for.

More than one variant could be present in this cat

DBE-NAD and Igor: PAX3, allele not published. More than one variant could be present in this cat: DBE-nad, Igor: PAX3, allele not published. It is not established that any of them is, and it is not established that two are. A dominant allele comes from a parent, and this cat's recorded ancestry carries an attribution of each. The attributions above it are on Ermine Trace Barkhat, Ermine Trace Enya, Ermine Trace Jeana, Ermine Trace Kashemir, Ermine Trace Lazurit, Ermine Trace Nadeya, Ermine Trace Olwen, Ermine Trace Qorall, Faberge Ermine Trace, Jaki Ami Sissy Crazy Blue, Leonardo De Cassis, Schoenweg Teodoro, Zarafina Ermine Trace, also written Ermine Trace Zarafina. A cat holding two is a compound heterozygote, which this survey records as the state associated with deaf and dead kittens, and nothing but a test distinguishes one from two.

Computed from the recorded parentage at every build, counting both the variants this survey adopts and the ones it records a source claiming and does not adopt. It is an upper bound and not a finding: it says what could be here, never what is.

What the pedigree implies

Possible carrier by descent. DBE-NAD, through Ermine Trace Barkhat, Ermine Trace Enya, Ermine Trace Lazurit; the Igor line, PAX3, allele not published, through Jaki Ami Sissy Crazy Blue, Leonardo De Cassis; the Nadeya line, DBE-NAD, though no traced descent from the genotyped founder reaches this cat, through CH Carajan zur Sternebucht, CH Dellary's Exoti Merlin, CH Du Blue D'or Argentin Nuance's Golden

This is computed from the recorded parentage each time this site is built and is not typed into the register. It is a deduction from the trait being dominant, not a statement by any source, and it is not the same thing as the record's own status field. Only a laboratory settles it for an individual. The full list is on latent lines.

What is flagged on this tree

  1. Ermine trace Nadeya. Attribution. The chart names this line's variant and this register had it as unidentified. Genealogy C13 is headed 'Nanotigr blue-eyed British shorthairs, DBE-ALT' and writes DBE-ALT in red beside Oliver, beside Amelia Nanotigr and beside Ermine trace Nadeya, who is the foundation cat of the Ermine Trace dominant blue-eyed line. The Ermine trace and Nanotigr cats are therefore attributed DBE-ALT by their own chart. It is an attribution and not a test: no Ermine Trace cat holds a laboratory result, and the only result ever held for Nadeya was a colourpoint test at the C locus, which this register corrected on 17 August 2026. The variant is recorded as claimed and not adopted, which is what the variant_claimed field is for, and the line stops being counted as a variant of its own | the variant is named and she is the cat it is named for, 12 September 2026. Abitbol M, Eisele T and Lipovenko E, 'Additional PAX3 Variants for Dominant Blue Eyes in Cats', Animal Genetics 2026;57:e70199, doi:10.1002/age.70199, open access, read 12 September 2026 names the allele DBE-NAD, Nadeya Dominant Blue Eyes, NC_058375.1:g.[205097674_207411974del;207411975_211290497inv;211290498_211387174del]. It is not a point change but a complex rearrangement, a deletion then an inversion then a second deletion, spanning about 6.3 million bases and taking PAX3 with it. She is recorded heterozygous. All 39 DBE cats of the line were heterozygous, all 47 controls of the line and breed were wild-type, and the allele was absent from every DBE cat of every other line tested. No Living homozygote has ever been found, which is the basis for the paper's statement that the homozygous genotype is likely lethal. The DBE-ALT attribution from chart C13 is withdrawn by this result and is no longer carried in any field: the chart said DBE-ALT, the genotype says DBE-NAD, and the genotype settles it. The chart remains named here as the source that said otherwise. Her parents were two registered British Shorthairs and neither was a dominant blue eye: the paper attributes the sire's blue eyes to colourpoint and gives the dam as green-eyed. S_PAX3_2026_234 | an english-language note on this line is in circulation and it is wrong. A 2026 update added to the translation of the cattery's own 2021 article states that testing has shown the Ermine Trace cats to carry DBE-ALT, and goes on to infer that DBE-ALT may be deeply embedded in the silver and golden British population and that cats registered 61 are more likely DBE-ALT. The published genotyping says the opposite. The line carries DBE-NAD, an allele found in no other line tested; all 39 dominant blue eyed cats of the line are heterozygous for it; and DBE-ALT is excluded, two Ermine Trace cats having already been genotyped wild-type for the DBE-CEL insertion in 2024 and the line being wild-type for DBE-ALT throughout. The inference drawn from the error is therefore unsupported too: nothing in the published work places DBE-ALT in the wider silver and golden British population on the strength of this line. The note is recorded here because a breeder reading it in English would otherwise act on it. Source: the Ermine Trace cattery's own published account of the line, 'Reviewing the dominant blue (DBE) gene in the Ermine Trace cattery', 2021, in English translation. A breeder statement and not a peer-reviewed source, and the counts in it are the cattery's own. S_ERMINE_238 | the one place this line meets another DBE line, and it is not a route for either variant. Oliver, the founder of the Nanotigr line, and this cat share 55 recorded ancestors, among them Eric von Buergersruh, who stands above both: he is the sire of Captain Ermine Trace, Oliver's great-great-grandsire, and he is Ermine Trace Olwen's great-grandsire. The two lines carry different published alleles: Nanotigr is DBE-ALT and this line is DBE-NAD, and neither allele appears in the other line on any test. The shared ancestry therefore cannot be the route for either, and 55 ancestors in common says only that both are bred from the same British chinchilla stock, which every British chinchilla cattery in Europe is. It is the clearest worked example this register holds of its own rule: shared ancestry is not a shared variant, and here two genotypes prove it rather than merely warn about it. Eric von Buergersruh was a widely-used sire, which is what makes him a common ancestor and not a source. S_ERMINE_238 | the Igor line does not stand above this cat, and it does stand below her. The founding tree of this line, 179 animals counting everything above Nadeya and above Oliver of the Nanotigr line together, contains not one record carried under an Igor label. Nothing of the Igor material is ancestral to her, which removes the only route by which her determinant could have arrived from that line and leaves the cattery's own account, a variant arising in her, standing. Below her it is the other way round: of the 30 cats that descend from her by unbroken parent links, 28 also have an ancestor carried under the Igor label, every one of those paths running through Leonardo De Cassis and Jaki Ami Sissy Crazy Blue, both of whom this register holds with no eye colour and no variant. The two halves say different things. Above her, the absence is evidence about where DBE-NAD came from. Below her, the presence is a compound heterozygote question and not an origin question, and one genotype on either of those two animals settles it. S_ERMINE_238 | the cattery has restated its own codes and the register holds the older form. Its public site, read 13 September 2026, gives this cat as BRI ns 11 08 61 where this register holds BSH ns 09 11 68, and the same substitution runs through its other cats: Barkhat as BRI as 11 33 08 against BSH as 09 11 33 68 here, Faberge as BRI ny 11 08 61 against BSH ny 09 11 68. The cattery is writing 08 where this register has 09, AND 61 where it has 68. Both pairs are eye and white markers in the same family of codes and the substitution is systematic rather than a slip. The register does not change its codes on a website reading: the codes held here come from pedigree sheets and certificates, and which form a registry recognises is the question case study one is about. Recorded so that the difference is not mistaken for an error in either source. S_ERMINE_238 | asked whether the determinant sits above her, the register answers from its own parent links. If cats carrying DBE-NAD existed that did not descend from her, it would have come from one of her parents. Not one does. Every record in this register that carries DBE-NAD descends from her by unbroken parent links. Her sire ch Schoenweg Teodoro has one other recorded offspring here, Ermine trace Kashemir, BSH ns 11, and Kashemir carries no eye code and no 33 to hide one, so his state is readable and he shows nothing. Her dam Ermine Trace Olwen, BSH ns 11, is likewise readable and shows nothing, and the cattery records that Olwen's own dam produced five kittens in three litters with nothing unusual in any of the others. The one animal above her whose state cannot be read is Teodoro himself, a colourpoint at ns 11 33, and the cattery counts about forty offspring by him before her, gold and silver, colourpoint and chinchilla, every one normal. A dominant determinant carried by a sire shows in about half his kittens and one in forty is not half. The determinant appears in her and not above her on everything this register holds. No cat showing the trait descends from Teodoro or from Olwen without also descending from her. S_ABOVE_247 | the question of whether the determinant sits above her is closed by a count of her sire's litters. CH Schoenweg Teodoro sired thirteen litters and she is the only dominant blue eye kitten in any of them. A dominant reaches about half of every litter, so a carrier sire would have shown it in nearly all thirteen. He did not carry it. Her dam is readable and shows nothing, her dam's dam produced five kittens in three litters with nothing unusual in any other, and every record in this register carrying DBE-NAD descends from her. The mutation arose in her. S_TEODORO_248 | she is a founder in the strict sense and not merely the earliest cat held. Both her parents' pedigrees are now held in full and both are empty of the trait: her sire gave thirteen litters with one dominant blue eye kitten in all of them, and her dam returns thirty ancestors over four complete generations with no eye code on any of them. The variant arose in her. That is what the published work reports as well, DBE-NAD being found in no other line tested. S_OLWEN_249 | the test that would break the founder reading was run on 13 SEPTEMBER 2026 and it did not break it. If the determinant came from a parent rather than arising in her, cats carrying it would exist that were born before her or that descend from something other than her. The register holds thirty-eight records carrying DBE-nad besides herself. Not one was born on or before 12 OCTOBER 2016. Not one fails to descend from her by unbroken parent links. The earliest is 10 November 2017, thirteen months after her. Two of the thirty-eight carry no date at all, Aquarelle Ermine Trace and Elina Ermine Trace, and both descend from her, so neither is a counter-example either. Twenty-four Ermine trace litters are now held with a date and every kitten in every one of them reaches her. S_LITTERS_250 | the timeline was tested on 13 SEPTEMBER 2026 and it holds at every step. A descent is only real if each cat is old enough to have bred when the next was born, and if each generation sits far enough below the one above it in time. Ninety-two records descend from her and one hundred and forty-three parent to kitten pairs carry a date on both sides. In every one of the 143 the parent is older by at least 300 DAYS. Not one kitten is born on or before a parent, and not one parent is too Young to have bred. The generations also sit where they should. Her own first generation begins 13 months after her, the second at 32 months, the third at 48, the fourth at 73 and the fifth at 101. The shortest possible spacing for five generations is about 50 months and the record uses 101, so the descent is not compressed against the calendar anywhere. Four records in the descent carry no date. S_LITTERS_250 | with the Emerald Flower branch re-lined on 13 SEPTEMBER 2026, no cat anywhere in this register shows the trait under the Nadeya label without descending from her. Wanessa and Paula Emerald Flower were the only two, they were labelled from a breeder chart, and Wanessa's own pedigree carries no Ermine Trace cat and no eye code on any of its twenty-eight ancestors. S_WANESSA_252 | the route by which the Emerald Flower branch touched this line has been traced and it carries nothing. Two animals appear in both bodies of material, Vitma Belle Gold and IC Silver Angel's Jantar, at the great-great-grandparent rank. Both pedigrees are now held and neither carries an eye code on any of its forty combined ancestors. S_SHARED_253 | the ALT material and this line do not meet by descent. No record in this register descends from both her and a DBE-ALT cat, no DBE-ALT cat stands below her, and none stands above her. The two variants share trace ancestors in the golden British foundation stock and nothing else. S_SHARED_253 | where this variant sits in PAX3. A third party compilation places DBE-NAD at not a point variant at all but a large structural one of about 6.29 megabases spanning the PAX3 REGION, described as a deletion, an inversion and a deletion. The register records the position and does not adopt it as its own finding: a schematic on a website is not a paper, and where this register needs the science it cites the papers directly. It is recorded because it is checkable, and because the position in the gene is the one thing about these variants that a breeder can never observe and a laboratory never reports on a result sheet. S_LOCI_272 | an outside count that agrees with this one. The same third party compilation holds eight named variants, DBE-CEL, DBE-ALT, DBE-re, DBE-AGO, DBE-Maru, DBE-nad, DBE-cDc and DBE-xHW, and states that six of them are characterised in peer-reviewed research. That is this register's position exactly: eight held, six published, and the two Chinese ones identified in 2025 but not published. Two compilations working from the same Literature and arriving at the same eight, and the same split between them, is worth recording because the count is the figure this survey is most often asked for. S_LOCI_272 | the split between the eight is not six identified and two unknown. It is six characterised in peer-reviewed research and two identified by a commercial laboratory that does not publish, with a test on sale for each of those two. The distinction matters to a breeder, who can buy a test for all eight of the identified variants and for none of the unidentified ones. S_CHINESE_273
  2. Ermine trace Lazurit. Outbred. Thirty ancestors of thirty possible and all thirty unique, coefficient of inbreeding 0.0 per cent on four complete generations. The doubling seen lower in this line does not come from him: his son Ermine Trace Jantar returns 6.25 per cent, and the repeated positions there enter through the dam, Ermine Trace Cherry, who is also out of Lemurcat Xantares | Code. He is registered 67, the pointed code, and the chart draws him with two blue eye icons. Code 67 attributes a blue eye to the Siamese gene. Both statements are recorded and neither is preferred
  3. Ermine trace Lazurit. Variant taken over high white, on a ruling and not on a test. This cat carries dominant white, a van, harlequin or bicolour figure, or a point figure, any of which leaves enough unpigmented iris to account for a blue eye without PAX3. It also carries a variant or stands in a DBE line, and the holder ruled on 31 August 2026 that the variant is taken as the cause in that situation. The alternative is not closed and only a genotype closes it. A photograph is better evidence of extent than a code, so where one has been read the phenotype note should be preferred to this flag. Recorded so the ruling is visible on every animal it touches and can be reversed as a set. S_VARIANT_OVER_WHITE
  4. Ermine trace Qorall. The highest coefficients of inbreeding in this register, and the doubled cat carries no eye code. Smile Ermine Trace returns 25.0 PER cent on twenty-two unique ancestors of thirty, and Tanatos Ermine Trace returns 20.3 PER cent on nineteen of thirty. In both cases Ermine trace Qorall, BSH ny 12, stands twice: he is the sire of Smile and also the sire of Smile's dam Zarafina, which is a father to daughter mating; and he is the sire of Tanatos's sire Xrustal AND the sire of Tanatos's dam Zarafina, which makes those two half-siblings. Ermine trace Nadeya, the founder, also stands twice on the Tanatos sheet. The register records this as a fact about the matings and not as a judgement. What it shows is that the coded cats of this line are being produced by doubling back onto the line, which is what a breeder does to fix a trait, and that the animal doubled is one that carries no eye code at all
  5. Ermine trace Enya. 68 AND 69 alternating down a single-source descent, in a second breed. On these five sheets the line runs Ermine trace Nadeya, BSH ns 09 11 68, to Ermine trace Enya, BSH ns 11 69, to Ermine trace Sapphire, BSH ns 09 12 68, to Ermine trace Jantar, BSH ny 09 25 68, to Nefertiti Ermine trace, BSH ny 25 69. Five generations and the code goes 68, 69, 68, 68, 69. The second branch does the same: Enya to Zarafina Ermine trace, BSH ny 11 68, to Faberge Ermine trace, BSH ny 09 11 68. Every sire brought in against these dams carries no eye code at all: Ermine Trace Kashemir BSH ns 11, Lusy-Mur Dionis BSH ay 11, Ermine Trace Qorall BSH ny 12, and no animal above any of them carries one either. There is no second source on these sheets. This is the Arst Venezia result reached again in a different breed and a different country: A single variant segregating in one line is sufficient to produce both codes. Nothing in this material has been genotyped
  6. Ermine trace Barkhat. Variant taken over high white, on a ruling and not on a test. This cat carries dominant white, a van, harlequin or bicolour figure, or a point figure, any of which leaves enough unpigmented iris to account for a blue eye without PAX3. It also carries a variant or stands in a DBE line, and the holder ruled on 31 August 2026 that the variant is taken as the cause in that situation. The alternative is not closed and only a genotype closes it. A photograph is better evidence of extent than a code, so where one has been read the phenotype note should be preferred to this flag. Recorded so the ruling is visible on every animal it touches and can be reversed as a set. S_VARIANT_OVER_WHITE | a colourpoint carrying DBE-nad, and so is his sire. His own certificate, read 13 September 2026, gives him as BRI as 11 33 08, blue silver shaded POINT with DBE-white, and his sire Ermine Trace Lazurit as BRI ns 12 33 08, silver chinchilla POINT with DBE-white. THE 33 is the colourpoint and the 08 is the DBE white: two separate causes of a pale eye written on one code, in one cat. This is the case the survey's pointing rule exists for. A colourpoint cat has blue eyes for an ordinary reason, so its dominant blue eye cannot be read off its face and can only be established by a test. The published genotyping found exactly this: of seven colourpoint cats of this line whose state could not be read, three carried the variant and four did not. S_ERMINE_238 | two names, one cat, and the register is holding both until the compiler rules. The cattery's litter page for F5 gives the sire of Faberge Ermine Trace as Ermine trace Velvet, BRI as 11 33, out of Ermine Trace Zarafina on 7 April 2022. Faberge's own certificate, gives the sire of the same kitten on the same date out of the same dam as Ermine trace Barkhat, BRI as 11 33. The codes are identical, the dam is the same and the date is the same. On the evidence these are one animal under two names. Nothing is folded: this register does not merge two records on an inference, and the fold would move three litters and their kittens onto a different parent. Awaiting the compiler's ruling. S_ERMINE_LITTERS_239 | entered from a photograph and a name, which is the thinnest basis this | his code and three litters came in on 13 SEPTEMBER 2026 and he is a colourpoint. BRI as 11 33, blue silver shaded point. THE 33 gives him blue eyes for an ordinary reason and hides whatever else he carries, so his own dominant blue eye state cannot be read and is not established. He is not recorded as a carrier. He sired litters Z4 out of Ermine Trace Athena, A5 out of Ermine Trace Enya and E5 out of Ermine Trace Laurika. The first two dams both carry DBE-nad, so every dominant blue eyed kitten in those litters is accounted for by the dam alone and nothing in them shows what he carries. His E5 litter, out of a dam with no eye code, produced two colourpoints and is equally silent. One test on him would settle all three. S_ERMINE_LITTERS_239 | two names, one cat, and the register is holding both until the compiler rules. The cattery's litter page for F5 gives the sire of Faberge Ermine Trace as Ermine trace Velvet, BRI as 11 33, out of Ermine Trace Zarafina on 7 April 2022. Faberge's own certificate, gives the sire of the same kitten on the same date out of the same dam as Ermine trace Barkhat, BRI as 11 33. The codes are identical, the dam is the same and the date is the same. On the evidence these are one animal under two names. Nothing is folded: this register does not merge two records on an inference, and the fold would move three litters and their kittens onto a different parent. Awaiting the compiler's ruling. S_ERMINE_LITTERS_239 | he is an obligate carrier, and the register's own test fires on him. The rule is that a cat which has produced the trait by two or more different mates, none of which shows it either, must itself carry it. He has done it by three. Boon Lora, a British Longhair of no Ermine Trace descent and no eye code, gave two showing kittens by him; Ermine Trace Nyusha, no eye code, gave one; Ermine Trace Plamia, no eye code, gave three of four. Three unrelated-enough dams, none showing, all producing the trait by the same sire. A dominant determinant cannot appear in those kittens from two parents that carry none, and the sire is the only factor common to all three litters. He is a colourpoint, as 11 33, which is exactly why nothing shows on him. The variant is adopted on the pedigree and not on a test, and one test on him would confirm it and would also settle the Barkhat identity question above. S_ERMINE_LITTERS_239 | the collision flagged on 13 SEPTEMBER 2026 is ruled and the two records are one cat. Ermine Trace Barkhat and Velvet Ermine Trace were held separately. Barkhat is the Russian word for Velvet, the cattery writes the name in Russian on its own litter pages and in English on the registry, and the two records return the same colour, the same dams, the same litter dates and the same kittens. Three kittens were held twice because of it and are merged with him: Angel Ermine Trace, Azia Ermine Trace and Gourami Blue Ermine Trace. The obligate carrier finding is strengthened, not weakened: the rule fired on three non-showing dams under the Velvet record, and Barkhat adds Faberge Ermine Trace out of Zarafina, a fourth. The code tail is the only disagreement, the registry writing 09 and 68 where the cattery writes neither, which is the split that runs through every Ermine Trace cat in this register. S_MERGE_241 | the merge is confirmed by the breeder's own stud book. The Northern Light Ermine Trace sheet, writes Ermine trace Barkhat, BRI as 11 33 08, as the sire of Gourami Blue Ermine Trace out of Plamia Ermine Trace. That is the Velvet colour code with the white figure added, under the English name, in a document the cattery wrote itself. One cat, two names, and the cattery uses both. S_SHEETS_242 | the merge is closed by velvet's own registration entry. It gives Velvet Ermine trace, BRI as 11 33 08, blue silver shaded point with DBE white, born 15 JANUARY 2020, sire Lazurit Ermine trace, dam Jeana Ermine trace. This record holds Ermine Trace Barkhat at BSH as 09 11 33 68, born 15 January 2020, out of Ermine Trace Lazurit by Ermine Trace Jeana. Same day, same sire, same dam, same colour. The white figure now agrees too, 08 on the Velvet entry against 09 on PawPeds being the only remaining difference in the tail. One cat. S_VELVET_244 | the complete recorded reproduction, set out as one cat for the first time. Nineteen kittens by seven dams. Three of the dams are themselves coded and so test nothing: Ermine Trace Athena, Zarafina Ermine Trace and Ermine Trace Enya. Four carry no eye code at all, and three of those four produced showing kittens by him. Plamia Ermine Trace, BRI ny 11, gave four and three of them show: Gourami Blue coded 61, Gourami Pearl 63, Graal 63. Boon Lora, BLH ny 11, gave four and two show: Quatis coded 68 and Quila 68. Ermine Trace Nyusha, BSH ny 12, gave three and one shows: X-Lily coded 68. The fourth, Ermine trace Laurika, BRI ny 12, gave two colourpoints and nothing readable. The rule is that a cat which produces the trait by two or more different mates, none of which shows it either, must itself carry it. He has done it by three, and eleven of his nineteen recorded kittens carry an eye code or a colourpoint code that hides one. He is a colourpoint, as 11 33, which is why nothing shows on him. S_CARRIER_245 | the obligate carrier claim on this cat is withdrawn, 13 SEPTEMBER 2026. The register held that he must carry the determinant because he produced it by three different mates, none of which shows it. The rule requires mates that cannot themselves be carrying it, and two of the three can. Nyusha Ermine Trace reaches Ermine Trace Nadeya through Ermine Trace Ulrika and Ermine Trace Egretka; Plamia Ermine Trace reaches her through Ermine Trace Yersella and Ermine Trace Lazurit. Either may be a latent carrier, and the published work on this line found carriers hiding under colourpoint coats, so that is the ordinary case here and not a remote one. The determinant in those two litters could have come from either parent. One mate is left, Boon Lora, who holds no recorded ancestry in this register and is not an Ermine trace cat, and one is not two. The claim is withdrawn and the earlier wording is kept above, not deleted. The grade does not move: he descends from the genotyped founder by unbroken parent links through Ermine Trace Lazurit, and DBE-NAD stands on him at lineage grade on that ground alone, which is where every other traced cat of this line stands. Nothing below him changes. S_WITHDRAW_246 | the finding is restored on a different and better basis than the one withdrawn earlier today. It no longer rests on counting mates. It rests on one documented and empty pedigree. Boon Lora's own sheet returns thirty ancestors over four complete generations and not one of them carries an eye code. She is BLH ny 11 with no code of her own and no 33 to hide one, so her state is readable and she shows nothing, and nothing on her sheet reaches the Ermine Trace line. She gave four kittens by this sire and two of them are coded 68, Quatis Ermine Trace and Quila Ermine Trace. The determinant is not available from her side, so it came from his. This is the argument the register already uses on Ermine Trace Jeana and on DriveGrad Dream, and it is stronger than the mate count because it rests on what a pedigree records rather than on what a phenotype fails to show. S_ABOVE_247 | a fourth document confirms the merge. The Azia Ermine Trace PawPeds sheet writes Ermine trace Barkhat, BSH as 09 11 33 68, born 15 January 2020, out of Ermine Trace Lazurit by Ermine Trace Jeana. S_AZIA_251
  7. Zarafina Ermine trace, also written Ermine trace Zarafina. The highest coefficients of inbreeding in this register, and the doubled cat carries no eye code. Smile Ermine Trace returns 25.0 PER cent on twenty-two unique ancestors of thirty, and Tanatos Ermine Trace returns 20.3 PER cent on nineteen of thirty. In both cases Ermine trace Qorall, BSH ny 12, stands twice: he is the sire of Smile and also the sire of Smile's dam Zarafina, which is a father to daughter mating; and he is the sire of Tanatos's sire Xrustal AND the sire of Tanatos's dam Zarafina, which makes those two half-siblings. Ermine trace Nadeya, the founder, also stands twice on the Tanatos sheet. The register records this as a fact about the matings and not as a judgement. What it shows is that the coded cats of this line are being produced by doubling back onto the line, which is what a breeder does to fix a trait, and that the animal doubled is one that carries no eye code at all | she is the dam on both high-coefficient sheets. Zarafina Ermine Trace is the dam of Smile at 25.0 per cent and of Tanatos at 20.3 per cent, and in both cases the sire is her own sire or her own half-brother | ruled and merged on 13 SEPTEMBER 2026, and the note that follows is what stood before the ruling. erm-11 is held as Ermine Trace Zarafina, BRI ny 12 61, born 29 November 2019, out of Ermine Trace Qorall by Ermine Trace Enya. pdb-31 is held as Zarafina Ermine Trace and is the recorded dam of Faberge. The cattery writes the prefix at either end of the name, which is how the two arose. Awaiting a ruling at that time. S_ERMINE_LITTERS_239 | Latency. Stated by a source, not demonstrated by a test. Latent is a claim that this cat carries a variant while showing no blue or odd eye, and here it rests on a breeder-compiled document rather than on a laboratory result. Three cats in this register are latent on a genotype: Belle Ayr Onyxx, DBE-ALT, and Robin and Rocky, both DBE-RE. This is not one of them | her own pedigree sheet, read 13 September 2026, gives her as BRI ny 12 61, born 29 November 2019, out of Ermine Trace Qorall by Ermine Trace Enya. The register held her with no parents and coded BSH ny 11 68; the sheet codes her ny 12 61 and both readings are kept. She is a granddaughter of Nadeya through Enya, and Teodoro stands twice in her four generations, once on each side. S_ERMINE_238 | two sources now call her blue eyed and the register had her as a latent. Her own pedigree sheet gives BRI ny 12 61 and the cattery's 2021 article gives BRI ny 11 61 and describes her as blue-eyed without visible white. THE 61 is the blue eye, so she shows the trait and is not latent. The earlier latent reading is kept on the record above and is not deleted, because it came from a source too. The two codes differ only in the 11 against the 12, which is the shaded against the tipped, not the eye. S_ERMINE_238 | ruled and merged on 13 SEPTEMBER 2026, and what follows is what stood before the ruling. erm-11 is held as Ermine Trace Zarafina, BRI ny 12 61, born 29 November 2019, out of Ermine Trace Qorall by Ermine Trace Enya. pdb-31 is held as Zarafina Ermine Trace and is the recorded dam of Faberge. The cattery writes the prefix at either end of the name, which is how the two arose. Awaiting a ruling at that time. S_ERMINE_LITTERS_239 | the collision flagged on 13 SEPTEMBER 2026 is ruled and the two records are one cat. erm-11 and pdb-31 carry the same sire, the same dam and the same birth day, 29 November 2019 out of Ermine Trace Qorall by Ermine Trace Enya. The cattery writes its prefix at either end of the name, which is how the two arose. The records are merged and the three codes are kept as their three sources write them. S_SHEETS_242 | the merge is confirmed by a third stud book sheet. The WoollyRays Iya Ermine Trace sheet writes Zarafina Ermine trace, BRI ny 11 61, as the dam of Faberge Ermine Trace out of Ermine Trace Barkhat, and gives her own parents as Ermine Trace Qorall and Ermine Trace Enya. One cat. S_SCOTTISH_243
  8. Faberge Ermine trace. 68 AND 69 alternating down a single-source descent, in a second breed. On these five sheets the line runs Ermine trace Nadeya, BSH ns 09 11 68, to Ermine trace Enya, BSH ns 11 69, to Ermine trace Sapphire, BSH ns 09 12 68, to Ermine trace Jantar, BSH ny 09 25 68, to Nefertiti Ermine trace, BSH ny 25 69. Five generations and the code goes 68, 69, 68, 68, 69. The second branch does the same: Enya to Zarafina Ermine trace, BSH ny 11 68, to Faberge Ermine trace, BSH ny 09 11 68. Every sire brought in against these dams carries no eye code at all: Ermine Trace Kashemir BSH ns 11, Lusy-Mur Dionis BSH ay 11, Ermine Trace Qorall BSH ny 12, and no animal above any of them carries one either. There is no second source on these sheets. This is the Arst Venezia result reached again in a different breed and a different country: A single variant segregating in one line is sufficient to produce both codes. Nothing in this material has been genotyped
  9. Lorenzo Ermine trace. The dominant blue eye has left the British breed in this litter. Both parents of this kitten are recorded on the cattery sheet with a Scottish code, and the sire Faberge Ermine Trace is British. The determinant is therefore in the scottish fold and scottish straight, not only the British Shorthair and Longhair. S_ERMINE_LITTERS_239
