How this cat connects, or does not connect, to an identified dominant blue eye variant. Generated from the register at build time.
What the proposed field says, and why it reads that way. A carrier of a variant with no published allele, on a line this proposal gives a suffix to. The scheme is set out in full in the proposal. No registry issues this field today: it is computed from this cat's record at each build, so it changes by itself the day a laboratory result is entered, and nothing here has to be reissued.
Superqueen is not in this cat's ancestry. The connection is a mating. This animal was bred to a cat of the Superqueen 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.
No line is named for this cat, and it nonetheless descends from a founder this register holds. The chain is reached by unbroken parent links.
The grade above and this trace are not in conflict. The grade describes what is known about the variant, and no source asserts one for this cat. The trace is parentage, assembled by this survey from the documents behind each step. A cat can have a fully documented descent and still have nothing said about which variant, if any, came down it.
| Generation | Cats held | Carrying a variant |
|---|---|---|
| 1 | 2 of 2 possible | none |
| 2 | 2 of 4 possible | none |
| 3 | 4 of 8 possible | none |
| 4 | 6 of 16 possible | none |
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.
