How this cat connects, or does not connect, to an identified dominant blue eye variant. Generated from the register at build time.
The proposed scheme writes no field for this cat. It codes carriers, and this animal is not recorded as one; where two causes of a pale eye stand together on a single record the scheme also leaves the cat unknown rather than coding it either way. The proposal sets out both cases.
Pedigree ancestry, not a DBE line is not in this cat's ancestry. The connection is a mating. This animal was bred to a cat of the Pedigree ancestry, not a DBE line line, or produced kittens with one, AND THAT IS ALL. It does not carry the line in its blood so far as this register can show, and any variant in that line reached its kittens through the other parent, not through this one.
There is no chain to draw, because this cat is not descended from the line. mated to Karina vom Wuerzburgerstern, who descends in the Igor line; this cat is named to Pedigree ancestry, not a DBE line by a source and no descent is recorded for either. A trace runs from a cat up through its parents to a founder. This cat has no such path: its link is sideways, through a mate, not upwards through ancestry. Nothing here says this animal carries anything.
No parentage is held for this cat at all. That is a gap in the record and not a statement about the animal.
This cat has never been tested. Everything above rests on documents and descent. Descent from a line is not a genotype. A cat can stand in a line and carry nothing, and a blue eye can be caused by white, by colourpoint or by low iris pigment with no PAX3 variant involved.
This is not a health certificate. It says nothing about hearing, and nothing about whether this cat should be bred from. Deafness in this trait is associated with carrying two different variants at once, which no pedigree can show and only a test can.
This directory is built from what people send it. For this cat it does not hold:
Sending a pedigree, a photograph or a test result. A pedigree has to be one a registry or club issued, because that is the only document that settles a parent; a breeder chart is welcome but is recorded at a lower grade and cannot draw a descent. The contact page says what to send and how. A correction is as welcome as an addition: where this page is wrong about your cat, the record is changed and the source you supply is named on it.
