The animal

Register id

Proposed variant field

Breed

Celeste line

Eye state

Sex

male

Born

not recorded

What the proposed field says, and why it reads that way. The variant is attributed to this animal from the record rather than from a result on it. 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.

What the register holds

Evidence grade

Line-traced — descent from a named founder is stated by the source

Variant

DBE-CEL

Line

None traced. This cat is named to the Celeste (Chatterie d'Aerlin) line by a source, and no descent is recorded

Connection

named to the Celeste (Chatterie d'Aerlin) line by a source; the register holds no parentage that shows it

The Celeste (Chatterie d'Aerlin) name on this cat is an attribution, not a traced descent. A source, usually a breeder-compiled chart, places it in that line. The register holds no chain of parentage that confirms or denies it.

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.

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.
