Omega Chatterie de Nice
prefix Chatterie de Nice · Siberian · line: Siberian, Altai or Barnaul unconfirmed · both eyes blue · Variant not known
Under the variant field this directory proposes, this cat would read DBE 161p. A carrier of a variant nobody has sequenced, on no named line. This is the group bare 161 exists for. 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
NO RECORDED PARENT LINK JOINS THIS CAT TO A FOUNDER OR TO A TESTED ANIMAL. What the record rests on instead is the line recorded on it, Siberian, Altai or Barnaul unconfirmed, which is a source's attribution and not a descent this register can walk.

More than one variant could be present in this cat
DBE, variant not named on the document and Siberian, Altai or Barnaul unconfirmed. MORE THAN ONE VARIANT COULD BE PRESENT IN THIS CAT: DBE, variant not named on the document, Siberian, Altai or Barnaul unconfirmed. 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 Bereginya Velikii Ohotnik, Blue Topaz Grilyazh, Blue Topaz Gusar, Blue Topaz Klukva, Blue Topaz Relax, Brusnika iz Odissei, Budur Tsarevna Barselit, CH Fluela Climberiada, Diran Climberiada, Glasha Taiga Star, Granat Auric, Lazy Climberiada, Murmur's Chipounette de L'Or, Murmur's Trilly, Myrtus Barselit of Murmur's, Neo Argo Chatterie de Nice, Neva's Legend Ignat, WCH (WCF) V*Grand Sineglaziy Angel, WCh (WCF) Milana Lion's Heart, Zakhar Taiga Star. 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
BLUE TOPAZ GRILYAZH. THE CHART READING IS CONFIRMED BY A REGISTRY SHEET. The C3 genealogy gave him out of Neva's Legend Ignat and Brusnika iz Odissei, and the PawPeds pedigree for Noa Artemis Chatterie de Nice gives the same two parents with dates, Neva's Legend Ignat SIB n 09 22 18 June 2008 and GIC Brusnika iz Odissei SIB n 09 24 5 July 2008. A BREEDER CHART AND A DATABASE AGREEING ON A PARENTAGE IS WORTH MORE THAN EITHER ALONE | HE AND BLUE TOPAZ GUSAR ARE LITTERMATES, both given 7 August 2009 out of the same pair, AND THE CHATTERIE DE NICE FOUNDATION DESCENDS FROM BOTH: from him through Lazy Climberiada on the sire side, and from Gusar through Blue Topaz Relax and Myrtus Barselit on the dam side. THE BLUE TOPAZ LINE IS THEREFORE DOUBLED AT THE FOUNDATION of that cattery, by two brothers
WCH (WCF) V*GRAND SINEGLAZIY ANGEL. A DOMINANT WHITE BLUE-EYED CAT IN THE ANCESTRY, AND WHY IT DOES NOT EXPLAIN THIS LINE. WCH (WCF) V*Grand Sineglaziy Angel, SIB w 61, stands in Omega Chatterie de Nice's third generation, and Sineglaziy is Russian for blue-eyed. IN A WHITE CAT A BLUE EYE CANNOT BE READ: it may be the white gene, it may be a variant, and inspection cannot separate them, WHICH IS WHY THE LINE IS TRACED. DOMINANT WHITE IS DOMINANT: a cat carrying W is a white cat. Omega is SIB n 03 23 and her son Pavel Chatterie de Nice is SIB n 09 24 61, AND NEITHER IS WHITE, so neither carries W, AND THE BLUE EYE IN THIS LINE CANNOT BE THE WHITE-CAT BLUE EYE COMING DOWN FROM HIM. A dominant gene cannot skip the coat it produces. WHAT REMAINS OPEN is that a cattery breeding deliberately for blue eyes may also have held a blue-eye factor NOT linked to W, which would pass to non-white descendants exactly as this one appears to have done. BOTH ARE RECORDED AND NEITHER IS ADOPTED
ZAKHAR TAIGA STAR. A DOMINANT WHITE BLUE-EYED CAT IN THE ANCESTRY, AND WHY IT DOES NOT EXPLAIN THIS LINE. WCH (WCF) V*Grand Sineglaziy Angel, SIB w 61, stands in Omega Chatterie de Nice's third generation, and Sineglaziy is Russian for blue-eyed. IN A WHITE CAT A BLUE EYE CANNOT BE READ: it may be the white gene, it may be a variant, and inspection cannot separate them, WHICH IS WHY THE LINE IS TRACED. DOMINANT WHITE IS DOMINANT: a cat carrying W is a white cat. Omega is SIB n 03 23 and her son Pavel Chatterie de Nice is SIB n 09 24 61, AND NEITHER IS WHITE, so neither carries W, AND THE BLUE EYE IN THIS LINE CANNOT BE THE WHITE-CAT BLUE EYE COMING DOWN FROM HIM. A dominant gene cannot skip the coat it produces. WHAT REMAINS OPEN is that a cattery breeding deliberately for blue eyes may also have held a blue-eye factor NOT linked to W, which would pass to non-white descendants exactly as this one appears to have done. BOTH ARE RECORDED AND NEITHER IS ADOPTED
GLASHA TAIGA STAR. SHE STANDS TWICE IN PAVEL CHATTERIE DE NICE'S PEDIGREE AND SHE IS WHY ITS COEFFICIENT IS 12.5 PER CENT. Both his sire Finist Ural Gems and his dam Omega Chatterie de Nice are out of her, so she and her entire ancestry are doubled. THAT ANCESTRY CARRIES THE DOMINANT WHITE BLUE-EYED CAT V*GRAND SINEGLAZIY ANGEL, SIB w 61, who is her grandsire and who therefore appears twice in Pavel's four generations. SHE CARRIES NO EYE CODE HERSELF, SIB n 09 24
OMEGA CHATTERIE DE NICE. A DOMINANT WHITE BLUE-EYED CAT IN THE ANCESTRY, AND WHY IT DOES NOT EXPLAIN THIS LINE. WCH (WCF) V*Grand Sineglaziy Angel, SIB w 61, stands in Omega Chatterie de Nice's third generation, and Sineglaziy is Russian for blue-eyed. IN A WHITE CAT A BLUE EYE CANNOT BE READ: it may be the white gene, it may be a variant, and inspection cannot separate them, WHICH IS WHY THE LINE IS TRACED. DOMINANT WHITE IS DOMINANT: a cat carrying W is a white cat. Omega is SIB n 03 23 and her son Pavel Chatterie de Nice is SIB n 09 24 61, AND NEITHER IS WHITE, so neither carries W, AND THE BLUE EYE IN THIS LINE CANNOT BE THE WHITE-CAT BLUE EYE COMING DOWN FROM HIM. A dominant gene cannot skip the coat it produces. WHAT REMAINS OPEN is that a cattery breeding deliberately for blue eyes may also have held a blue-eye factor NOT linked to W, which would pass to non-white descendants exactly as this one appears to have done. BOTH ARE RECORDED AND NEITHER IS ADOPTED | HER OWN CODE DIFFERS BETWEEN SOURCES. This register holds her as SIB n 09 23 61 from earlier material and THE PAWPEDS SHEET GIVES SIB n 03 23, with a different white code and no 61. The register keeps the fuller reading and records the difference | THE BLUE TOPAZ LINE STANDS IN HER FOURTH GENERATION. CH Blue Topaz Grilyazh and W.Ch Blue Topaz Relax are both on her sire side and both are already in this register from the C3 chart, under the line 'Siberian, Altai or Barnaul unconfirmed'. THIS IS THE FIRST RECORDED PARENT LINK JOINING THAT MATERIAL TO THE CHATTERIE DE NICE LINE, and through her to the Great Joy cats and to Bonnie of Siberian Paws
OMEGA CHATTERIE DE NICE. Eye and coat, A DETERMINATION AND NOT A QUERY. This cat is blue-eyed in both eyes, carries a bicolour or locket white code, is not dominant white and is not colourpointed. THE CLASSIC WHITE SPOTTING GENE COVERS AN EYE WHERE THE WHITE HAPPENS TO FALL, WHICH GIVES AN ODD EYE AND NOT TWO BLUE ONES, so the coat does not account for this and a dominant blue eye is present in the line. IT IS NOT THE KIT ODD-EYE CASE. Its registry has entered no dominant eye code on it. WHICH VARIANT IS NOT DEDUCIBLE FROM A COAT CODE and none is adopted.
A flag is not an error. It marks a place where two sources say different things, or where an attribution cannot be made on the evidence held.

LOOF pedigree P19 for her daughter Pamela gives her as the dam, and the top-cat.org entry for Pavel gives her as his dam. The survey's earlier reading, that a shared letter made her their sister, misread the cattery's naming: The Chatterie de Nice cattery names by a letter per year of birth: N in 2017, O in 2018, P in 2019, R in 2020, S in 2021.

This directory is a working aid compiled from published charts, registry documents and breeder statements. It is not a register and it has no standing of any kind. The grade attaches to the animal, not to the line: a cat whose ancestor was genotyped is line-traced, not genotyped.
