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.

What the register holds

Evidence grade

Reported — asserted, with neither a test nor a traced descent

Variant

none identified for this cat

The trace

The founders this cat descends from

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.

RE (Rociri's Elvis)

1. Gimli
   MCO ds 22 · not-blue
2. BelleAyr O'Blue Pearl
   MCO ds 09 11 69 · odd-variant
3. Joyfield's Survivor van Nous Deux
   MCO es 03 68 · blue-variant
4. Joyfield's Dolly
   MCO g 09 68 · blue-variant
5. Rociri Elvis, given on the pedigree as Rociri's Elvis — the founder
   MCO e 09 68 · blue-variant

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.

Recorded ancestry, 4 generations

What this page does not establish

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.

What would change this page

This directory is built from what people send it. For this cat it does not hold:

• a test result for this cat, which is the only thing that settles which variant, if any, it carries
• a photograph, which settles an eye colour and the extent of any white far better than a code does
• a registry or club issued pedigree reaching further back, because the chain held here stops before a founder

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.
