British Gems Callista

prefix British Gems · British Shorthair · both eyes blue · No variant and no line attributed

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 no recorded parent at all, which is a gap in the sources and not a statement that the cat had none.

No parent is recorded for this cat in the register, so no genealogy can be drawn. That is a gap in the sources, not a statement that the cat had none. Any offspring the register holds are listed below.

What is flagged

1. BRITISH GEMS CALLISTA. A BREEDER SETTING OUT, IN HER OWN WORDS, THE WHOLE DISTINCTION THIS REGISTER WORKS TO. THE PAGE SEPARATES TWO THINGS. RECESSIVE ODD EYE: autosomal recessive, THE GENE MUST COME FROM BOTH PARENTS, associated with S piebald white spotting, carried silently for generations, NO HEARING PROBLEMS because it has nothing to do with the pure white gene, and recognised by FIFe for normal bicolour since 2019 and by LOOF and WCF. DOMINANT ODD EYE: ONE PARENT ONLY, a cat with 'minimal white variegation, a small white spot of a size of a hazelnut to a coffee saucer, and two intense blue eyes, odd, OR POLYCHROMIC, OR LATENT, non-expression of blue eyes but still carrier-dominant'. THAT IS EVERY CATEGORY THIS REGISTER USES, WRITTEN OUT BY A BREEDER | 'LATELY DOMINANT ARE GETTING LESS AND LESS WHITE, SOMETIMES NO WHITE IS VISIBLE ANYMORE.' That is the direct explanation of what this register has been seeing on British Gems Stitch, British Gems Alora, King Pride Mikado and the SoloMiya cats: coded animals with a locket or nothing, where the older material carries 01, 02 and 03 | 'DBE KITTENS IN SOLID COLORS WITH POSSIBILITY OF A LOCKET, A WHITE SPOT THAT IS A TRAITMARK OF THE GENES, OFTEN LOCATED IN THE NECK, ON THE TOES OR FACE.' The locket is not an accident that the code fails to record. THE BREEDER CALLS IT A MARK OF THE VARIANT ITSELF | AND IT NAMES THE PROBLEM THIS REGISTER KEEPS RUNNING INTO. 'SINCE THERE IS NO EMS CODE FOR THESE CATS, IT IS NOT VISIBLE IN PEDIGREE AND MISTAKES CAN EASILY HAPPEN.' Also: 'Solid odd eyed is not yet registered and will get RIEX experimental pedigree.' THAT IS WHY 61 IS BEING WRITTEN WHERE 68 IS MEANT, and why the coded cats of these catteries are absent from the registry listings | THE SOURCE OF THE DOMINANT IS NAMED. 'To obtain these genes and eye color it is necessary that the pedigree cat is crossed with an ALTAI, OJOS AZULES OR TOPAZ cat, THESE ARE THE LINES THAT EXIST IN DOMINANT. The first blue-eyed cats were discovered among stray cats in KAZAKHSTAN'S ALTAY REGION IN THE 1990s.' THAT PARAGRAPH IS THE BREEDER RESTATING WHAT THE PUBLISHED WORK ALREADY ESTABLISHES, not an independent confirmation of it. Abitbol and others 2024 report FOUR VARIANTS AND MULTIPLE UNMAPPED LINES, and this register holds that paper. THE PAGE'S VALUE IS AS EVIDENCE OF WHAT BREEDERS UNDERSTAND AND REPEAT, which is a different and also useful thing

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.

The description held

RED AND WHITE BICOLOUR WITH TWO BLUE EYES, photographed outdoors in daylight at close range. THE RED PIGMENT COVERS THE TOP OF THE HEAD AND BOTH ORBITS: the fur immediately around each eye is red, and the white runs as a blaze BETWEEN the eyes and down the muzzle, chest, belly and legs. She is not dominant white and not colourpointed. THE WHITE IS NOT WHERE IT WOULD HAVE TO BE TO HAVE PALED EITHER EYE, AND BOTH EYES ARE BLUE. NO EMS CODE EXISTS FOR HER in this register, so the coat test cannot be run and the reading rests on the photograph

Evidence grade

Reported asserted, with neither a test nor a traced descent

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.
