British Shorthair · line: Nanotigr · no blue eye. Carrier status not known · Variant known, this cat untested
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 the line recorded on it, Nanotigr, which is a source's attribution and not a descent this register can walk; and a variant a source attributes to it, DBE-ALT, which this survey does not adopt.
DBE-ALT. Exactly one variant below this cat is fixed by a DNA genotype or by a first-degree lineage genotype, through Belle Ayr Olympas, Cotomodda Hubba-Bubba, Belle Ayr O'Turner, and the name travels back up the path the deduction came down. THIS NAMES THE VARIANT AND DOES NOT UPGRADE THE CARRIAGE: what changed is which test to order.
ONE OF AN OBLIGATE PAIR. Paired with Amelia Nanotigr, for Roddiffer Afina
This is computed from the recorded parentage each time this site is built and is not typed into the register. It is a deduction from the trait being dominant, not a statement by any source, and it is not the same thing as the record's own status field. Only a laboratory settles it for an individual. The full list is on latent lines.
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.
breeder-compiled genealogy C13, 'Blue Eyed British Shorthair Line (Nanotigr line)', close-ups read 13 August 2026
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.
