prefix British Gems · British Shorthair · one blue eye · 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.
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.
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 British Gems cattery's own published article 'Genetics of odd eyed', british-gems.com/geneticsofoddeyed, read 25 August 2026. A BREEDER'S PERSPECTIVE AND NOT A SOURCE OF AUTHORITY. It opens 'I also want to mention that I AM NOT A GENETICIST. I wrote this article after research and from personal experience', and this register grades it accordingly: it is evidence of WHAT ONE BREEDER BELIEVES AND PRACTISES, and of the vocabulary in use among the catteries this register tracks, AND IT IS NOT EVIDENCE OF THE GENETICS. Where it restates published work, the published work is held in this register's own bibliography and is cited from there. It sets out RECESSIVE and DOMINANT odd eye as two separate things, names ALTAI, OJOS AZULES AND TOPAZ as the sources of the dominant, cites PROFESSOR MARIE ABITBOL of the Vetagro research laboratory for a list of breeding recommendations, and carries photographs including one captioned 'British gems Sophie: split odd eyed at both sides'
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.
