Under the variant field this directory proposes, this cat would read DBE 164t. A laboratory result on this animal. 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
A laboratory has tested this animal itself, so nothing has to be traced: the result is on the cat.

What is flagged on this tree
ANVERSCOON GRENACHE. Resolved. WHICH PARENT IS THE SIRE IS NOW SETTLED BY A CHART. The register previously held both of this cat's parents as dams. The PawPeds pedigree for Joyfield's Survivor van Nous Deux read 17 August 2026 places MAINEFIELD'S OYE COMO VA IN THE SIRE POSITION and Aislinn's Exciting Blue in the dam position
ROCIRI ELVIS, GIVEN ON THE PEDIGREE AS ROCIRI'S ELVIS. HIS OWN SHEET, AND WHAT IS AND IS NOT ON IT. THIRTY ANCESTORS, ALL THIRTY UNIQUE, FOUR COMPLETE GENERATIONS, INBREEDING 0.0 PER CENT. THE 68 ON HIM IS THE ONLY 68 ON THE WHOLE DOCUMENT AND THE ONLY EYE CODE OF ANY KIND ON IT IS THE 63 ON JUSTCOONS HA SHISCH, MCO w 63, A DOMINANT WHITE ODD-EYED CAT IN THE THIRD GENERATION. His grandsire Mainefield's Oye Como Va is MCO w, also white, and carries no eye code. NO OTHER ANIMAL ON THE SHEET CARRIES AN EYE CODE AT ALL. THAT IS THE WHOLE OF THE EVIDENCE ABOVE HIM: two white cats, one of them odd-eyed, and twenty-eight animals with nothing recorded about their eyes. In a white cat an eye cannot be read either way, so the sheet neither supplies a source for his 68 nor rules one out, WHICH IS WHY THE PUBLISHED TRACE ABOVE HIM RUNS THROUGH WHITE CATS AND GOES COLD THERE
JOYFIELD'S SURVIVOR VAN NOUS DEUX. Panel. The result that named this cat's variant came from a panel of four: DBE-ALT, DBE-RE, DBE-CEL and DBE-AGO. DBE-cDc AND DBE-xHW WERE NOT ON IT, so a second variant from those two would not have been seen
BELLEAYR OBLUE SKY. THE STRONGEST EVIDENCE IN THIS REGISTER THAT 68 AND 69 ARE ONE VARIANT, AND IT RESTS ON A GENOTYPE AND NOT ON AN INFERENCE. THREE FULL SISTERS, ONE MATING, 14 SEPTEMBER 2022, out of Joyfield's Survivor van Nous Deux, MCO es 03 68, and Justcoons Ohio State, MCO ds 22. ALL THREE ARE GENOTYPED DBE-RE. THE REGISTRIES CODED THEM THREE DIFFERENT WAYS: BELLEAYR O'BLUE SKY IS MCO ds 11 68, BELLEAYR O'BLUE SEA IS MCO ds 09 11 WITH NO EYE CODE AT ALL, AND BELLEAYR O'BLUE PEARL IS MCO ds 09 11 69. Two of the three are blue-eyed and one is odd-eyed. ONE ALLELE, CONFIRMED BY TEST ON EACH ANIMAL SEPARATELY, PRODUCED A 68, A 69 AND A BLANK IN ONE LITTER. THE ARST VENEZIA DESCENT AND THE ERMINE TRACE SHEETS REACH THE SAME CONCLUSION BY READING CODES DOWN A PEDIGREE; THIS LITTER REACHES IT FROM THE LABORATORY. It is therefore the primary evidence in this register on the question and those are the corroboration. IT ALSO SHOWS THAT AN ABSENT EYE CODE IS NOT AN ABSENT VARIANT: O'Blue Sea is blue-eyed, genotyped, and carries no eye code, so EVERY COUNT IN THIS REGISTER DRAWN FROM EYE CODES UNDERSTATES
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.

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.
