Blue Ridge Ocean Depths

prefix Blue Ridge · Maine Coon · line: Blue Eyed Maine Coons (Markiss) · one blue eye · Variant known, this cat untested · also in its ancestry: DBE-ALT, DBE-CEL

Under the variant field this directory proposes, this cat would read DBE 162|163p. A carrier with no result of its own and more than one identified variant above it. One test resolves it. The proposal is set out in full here, and no registry issues this field today: it is computed from the record at each build and is not part of any registration.

How this cat is connected to the trait

1. Blue Ridge Ocean Depths, XLH d 09 69
2. Blue Ridge David, XLH e 09 68, the sire of Blue Ridge Ocean Depths
3. Blue Ridge Charizard, XLH n 09 68, the sire of Blue Ridge David
4. Blue Ridge Tamara, XLH n 09 68, the dam of Blue Ridge Charizard
5. Nikita'l Markiss [Cherkassy, UA], XLH ns 03 68, the sire of Blue Ridge Tamara
6. Nikita'l Seymour, XSH ns 03 23 68, the sire of Nikita'l Markiss [Cherkassy, UA]. DBE-ALT, adopted by this survey; a founder of this survey

That is 5 recorded parent links, and the animal at the end of it carries a variant this survey has adopted, but has not itself been tested. 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.

More than one variant could be present in this cat

DBE-ALT and DBE-CEL. MORE THAN ONE VARIANT COULD BE PRESENT IN THIS CAT: DBE-ALT, DBE-CEL. 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 Nikita'l Seymour, Roxi. 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 is flagged on this tree

1. NIKITA'L MARKISS [CHERKASSY, UA]. THE FOUNDER HIMSELF SPLIT A LITTER 68 AGAINST 69, AND THIS IS THE EARLIEST SPLIT IN THE REGISTER. BLUE RIDGE IOLA, XLH n 09 68, AND BLUE RIDGE IOMA, XLH n 09 69, ARE BOTH GIVEN 26 APRIL 2018 OUT OF NIKITA'L MARKISS AND CELEBRITY. One litter, one sire, one dam, and the registry wrote 68 on one kitten and 69 on the other. CELEBRITY IS MCO n WITH NO EYE CODE, and neither A'Mars nor Blue Ridge Ingrid above her carries one, nor does any of her four recorded great-grandparents. THE DAM CONTRIBUTES NOTHING AND THE SPLIT IS THE SIRE'S | THIS IS THE THIRD SPLIT LITTER DOCUMENTED IN THIS CATTERY AND THE OTHER TWO ARE BY HIS GRANDSON BLUE RIDGE URBAN, on 22 June 2020 and 24 October 2020. THE PATTERN IS PRESENT AT THE FOUNDER AND STILL PRESENT TWO GENERATIONS BELOW HIM. A SINGLE VARIANT SEGREGATING FROM ONE ANIMAL IS SUFFICIENT TO PRODUCE BOTH CODES, and no second source is available in any of the three matings | THEIR SHEETS ALSO SHOW WHY MARKISS CANNOT BE TRACED FURTHER: every cell above Nikita'l Seymour, Eliza, Roxi and March Nikita'l reads 'No information in the database'. NOTHING IN THIS MATERIAL HAS BEEN GENOTYPED | A NAME SWEEP FOR NIKITA ACROSS THE BRITISH SHORTHAIR RETURNS NOTHING, AND THAT IS WORTH RECORDING. A PawPeds search on the given name Nikita, supplied 25 August 2026, returns SIXTY-SEVEN British Shorthair, British Longhair, Scottish Fold, Persian and Selkirk animals across fifty-odd unrelated prefixes. NOT ONE CARRIES 68, 69 OR 61. The eye codes present are 62 on four dominant white cats, 64 on two, and 33 or 03 white codes with no eye code at all. NIKITA IS A COMMON GIVEN NAME AND NONE OF THESE CATS CARRIES THE NIKITA'L PREFIX, which is a Ukrainian cattery breeding experimental shorthair and longhair and not British Shorthair. THE SWEEP IS ENTERED AS A NEGATIVE RESULT: the Nikita'l material is not hiding under this name in the British Shorthair, and the document still wanted is the CATTERY LISTING FOR THE NIKITA'L PREFIX, not a name search | THE NIKITA'L PREFIX LISTING HOLDS TWO CATS AND THEY ARE THE TWO FOUNDERS. Nikita'l Pheer-Ca XSH n 24 69 and Nikita'l Seymour XSH ns 03 23 68, AND NOTHING ELSE. Not one offspring is registered under the prefix and NIKITA'L MARKISS HIMSELF IS NOT ON IT. THIS WAS THE HIGHEST VALUE OUTSTANDING DOCUMENT IN THE SEARCH FOR A SECOND CROSSING OF THE ALT AND CEL LINES, because both founders demonstrably stood in this cattery together and any further litter of theirs would have been a crossing the register could not see. THE ANSWER IS THAT THERE IS NOTHING TO SEE: the registry holds no descendants of this prefix at all | WHAT THE REGISTER ALREADY HOLDS IS THEREFORE THE WHOLE OF THE RECORDED MATERIAL. Seymour by Pheer-Ca gives NIKITA'L MARKISS, the first crossing. Seymour by March Nikita'l gives KAENA, who was mated to LAZULI and gives the second. Seymour by Silva gives NIKITA'L DAISY. All three parentages come from pedigree sheets and breeder charts and NONE OF THEM FROM THE PREFIX LISTING, because the prefix listing has none | THE PREFIX IS CLOSED AND SHOULD NOT BE CHASED AGAIN. What remains unanswerable from paper is not whether more litters were registered, but whether any were bred and never registered, AND NO DOCUMENT CAN SETTLE THAT | THE NIKITA'L MATERIAL IS NOW CONFIRMED COMPLETE BY THREE REGISTRY SHEETS READ INDEPENDENTLY. Seymour's own sheet gives PUSHOK, HCL e 22 62, and ELIZA, XSH ns 02 69, and nothing above either. Pheer-Ca's gives ROXI, XXH n 24 68, KZ, and MARCH NIKITA'L, EUR n 03 62, and nothing above either. Markiss's gives all four. ON ALL THREE SHEETS EVERY CELL ABOVE THOSE FOUR READS 'No information in the database' | THE FOUR FOUNDATION ANIMALS ARE THE TOP OF THIS MATERIAL BY REGISTRY RECORD AND NOT BY ABSENCE OF SEARCHING. Taken with the cattery listing, which holds the two founders and no descendants at all, THE WHOLE OF WHAT ANY REGISTRY HOLDS ON THIS CATTERY IS NOW IN THIS REGISTER. Nothing further can be obtained from pedigree material and the prefix should not be chased again | TWO CODES STAND ON EACH SIDE OF MARKISS BEFORE HE IS BORN. His sire Seymour is 68 out of a 62 and a 69; his dam Pheer-Ca is 69 out of a 68 and a 62. THAT IS WHY EVERY LINE DESCENDING FROM HIM CARRIES BOTH, and it is visible on the sheet without any inference at all
2. BLUE RIDGE TAMARA. BLUE RIDGE TAMARA IS CONFIRMED BY A REGISTRY, AND SHE WAS THE LAST PEDIGREE THIS REGISTER WAS WAITING ON. Her descent from NIKITA'L MARKISS was held on a breeder-compiled chart only, and every Blue Ridge line running through her hung on that single unverified link. THE BLUE RIDGE QUASAR NEW SHEET PRINTS HER IN THE THIRD GENERATION AS XLH n 09 68, OUT OF NIKITA'L MARKISS [Cherkassy, UA], XLH ns 03 68, AND BIG KITTY HELLO KITTY, MCO n. A registry now says what the chart said | THE DESCENT BELOW HER IS FIVE GENERATIONS OF 68 WITH NOTHING COMING IN. Markiss 68, to Tamara 68, to BLUE RIDGE CHARIZARD XLH n 09 68, to BLUE RIDGE DAVID XLH e 09 68, to BLUE RIDGE QUASAR NEW XLH n 09 68 and BLUE RIDGE ODYSSEY XLH ds 09 68. EVERY DAM BROUGHT IN AGAINST THAT LINE CARRIES NO EYE CODE: Blue Ridge Oxxxymiron MCO n, Mainelynx Nesmeya MCO fs, Blue Ridge Yankee MCO n 09, Blue Ridge Quilty Girl MCO fs, and nothing above any of them. THE QUASAR NEW SHEET RETURNS THIRTY UNIQUE ANCESTORS OF THIRTY AT 0.0 PER CENT, so this is not a line doubled back on itself. IT IS ONE ALLELE TRAVELLING DOWN FIVE GENERATIONS OF OUTCROSSES
3. BLUE RIDGE CHARIZARD. BLUE RIDGE TAMARA IS CONFIRMED BY A REGISTRY, AND SHE WAS THE LAST PEDIGREE THIS REGISTER WAS WAITING ON. Her descent from NIKITA'L MARKISS was held on a breeder-compiled chart only, and every Blue Ridge line running through her hung on that single unverified link. THE BLUE RIDGE QUASAR NEW SHEET PRINTS HER IN THE THIRD GENERATION AS XLH n 09 68, OUT OF NIKITA'L MARKISS [Cherkassy, UA], XLH ns 03 68, AND BIG KITTY HELLO KITTY, MCO n. A registry now says what the chart said | THE DESCENT BELOW HER IS FIVE GENERATIONS OF 68 WITH NOTHING COMING IN. Markiss 68, to Tamara 68, to BLUE RIDGE CHARIZARD XLH n 09 68, to BLUE RIDGE DAVID XLH e 09 68, to BLUE RIDGE QUASAR NEW XLH n 09 68 and BLUE RIDGE ODYSSEY XLH ds 09 68. EVERY DAM BROUGHT IN AGAINST THAT LINE CARRIES NO EYE CODE: Blue Ridge Oxxxymiron MCO n, Mainelynx Nesmeya MCO fs, Blue Ridge Yankee MCO n 09, Blue Ridge Quilty Girl MCO fs, and nothing above any of them. THE QUASAR NEW SHEET RETURNS THIRTY UNIQUE ANCESTORS OF THIRTY AT 0.0 PER CENT, so this is not a line doubled back on itself. IT IS ONE ALLELE TRAVELLING DOWN FIVE GENERATIONS OF OUTCROSSES
4. MAINELYNX NORRIS. A BROTHER AND SISTER MATED IN THE NEXT GENERATION BUT ONE. He and Mainelynx Nesmeya are given the same two parents and the same date of birth on all five sheets, so they are littermates. His daughter Blue Ridge Quilty Girl was mated to her son Blue Ridge David, producing Blue Ridge Ocean Depths. THE DATABASE STILL REPORTS 0.0 PER CENT INBREEDING ON EVERY ONE OF THE FIVE SHEETS, because the shared ancestors fall outside the four-generation window the figure is computed over. A published coefficient is a statement about a window and not about an animal
5. BLUE RIDGE DAVID. BLUE RIDGE TAMARA IS CONFIRMED BY A REGISTRY, AND SHE WAS THE LAST PEDIGREE THIS REGISTER WAS WAITING ON. Her descent from NIKITA'L MARKISS was held on a breeder-compiled chart only, and every Blue Ridge line running through her hung on that single unverified link. THE BLUE RIDGE QUASAR NEW SHEET PRINTS HER IN THE THIRD GENERATION AS XLH n 09 68, OUT OF NIKITA'L MARKISS [Cherkassy, UA], XLH ns 03 68, AND BIG KITTY HELLO KITTY, MCO n. A registry now says what the chart said | THE DESCENT BELOW HER IS FIVE GENERATIONS OF 68 WITH NOTHING COMING IN. Markiss 68, to Tamara 68, to BLUE RIDGE CHARIZARD XLH n 09 68, to BLUE RIDGE DAVID XLH e 09 68, to BLUE RIDGE QUASAR NEW XLH n 09 68 and BLUE RIDGE ODYSSEY XLH ds 09 68. EVERY DAM BROUGHT IN AGAINST THAT LINE CARRIES NO EYE CODE: Blue Ridge Oxxxymiron MCO n, Mainelynx Nesmeya MCO fs, Blue Ridge Yankee MCO n 09, Blue Ridge Quilty Girl MCO fs, and nothing above any of them. THE QUASAR NEW SHEET RETURNS THIRTY UNIQUE ANCESTORS OF THIRTY AT 0.0 PER CENT, so this is not a line doubled back on itself. IT IS ONE ALLELE TRAVELLING DOWN FIVE GENERATIONS OF OUTCROSSES
6. BLUE RIDGE QUILTY GIRL. BLUE RIDGE URBAN HAS THREE SPLIT LITTERS BY THREE DIFFERENT DAMS, AND THAT IS A REPEATED CROSS. Out of BLUE RIDGE QUILTY GIRL, 22 June 2020: Gold Aquamarine XLH fs 68 and Grymza XLH fs 09 69. Out of BLUE RIDGE NANA, 24 October 2020: Young Maru XLH n 09 68 and Yoppie XLH ns 09 69. Out of BLUE RIDGE FENYA, 24 February 2021: GAVR XLH ns 25 68 AND GALAXY MCO ns 22 69. THREE MATINGS, THREE UNRELATED DAMS, AND EVERY LITTER CONTAINS ONE OF EACH CODE | TWO OF THE THREE DAMS SUPPLY NOTHING. Blue Ridge Quilty Girl is MCO fs and Blue Ridge Fenya is MCO fs 25, NEITHER CARRIES AN EYE CODE, and neither does any of the fourteen animals recorded above either of them: the Jordan Don Coon, Werona Irsaline, Mainelynx and Irsaline Afonya cats on Fenya's side are silent throughout. Only Nana is coded, at 69, and she is herself out of Nikita'l Markiss | THE SHEETS ARE CLEAN OUTCROSSES. Gavr and Galaxy each return THIRTY UNIQUE ANCESTORS OF THIRTY AT 0.0 PER CENT, so nothing here is the product of a line doubled back on itself. THE ONLY THING THE TWO KITTENS DIFFER IN THAT ANY DOCUMENT RECORDS IS THE NUMBER THE REGISTRY WROTE ON THEM | WHAT THAT ESTABLISHES. A single variant segregating from ONE SIRE produces both codes, and it has now done so three times in this cattery, once in the Nikita'l cattery by the founder himself, and once in the Ermine Trace cattery in a different breed. FIVE SPLIT LITTERS ACROSS THREE CATTERIES AND TWO BREEDS. This is the strongest pedigree evidence in the register on the question and only the BelleAyr genotypes outrank it, where three full sisters tested DBE-RE were coded 68, 69 and nothing at all
7. BLUE RIDGE OCEAN DEPTHS. THE SIRE THE WHOLE OF THIS MATERIAL RUNS THROUGH. Five pedigrees read 19 August 2026 give him as the sire, and the cats out of him carry 68 and 69 in the same litter. HE IS CODED 69 AND HIS SIRE, GRANDSIRE AND GREAT-GRANDDAM ARE ALL CODED 68, four generations of dominant codes in a straight sire line with no genotype anywhere in it. A LITTER OF THREE THAT SPLITS 68 AND 69. Hanfors world Hennessy, MCO a 03 68, Hanfors world H'Serafim, MCO d 03 68, and Hanfors world H'Xavier, XLH d 03 69, are all out of Blue Ridge Ocean Depths and Star Leader Nensi and ALL BORN 18 APRIL 2022. Two are coded blue and one odd. THAT IS WHAT ONE VARIANT SEGREGATING WOULD LOOK LIKE AND IT IS ALSO WHAT TWO WOULD LOOK LIKE. Their sire is coded 69 and their dam carries no eye code at all. NO ANIMAL IN THE LITTER HAS BEEN GENOTYPED and nothing is concluded. A panel on any one of the three would be worth more to this question than any further pedigree
