GIC Mary B Frodo of Barbarina

prefix Mary B · Maine Coon · line: Pedigree ancestry, not a DBE line · 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.

How this cat is connected to the trait

1. GIC Mary B Frodo of Barbarina, MCO w 63
2. GC Mary B Gandalf, MCO w 62, the sire of GIC Mary B Frodo of Barbarina. a founder of this survey; no variant has ever been identified in this line

That is one recorded parent link, and the animal at the end of it has never been tested, so the connection is a descent and not a result. Every step is a parent recorded in this register from a document; none of them is an assumption. The full genealogy is drawn below, and the sources for each animal are on its own page.

What it would be carrying

DBE-RE. Exactly one variant below this cat is fixed by a DNA genotype or by a first-degree lineage genotype, through BelleAyr Pluto, BigBoots Belle Azure, BigBoots Big T, 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.

What the pedigree implies

ON THE PATH ABOVE AN OBLIGATE PAIR. Above Rociri Elvis, given on the pedigree as Rociri's Elvis

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.

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.
