BigBoots Big T

prefix BigBoots · Maine Coon · DBE-RE · line: Rociri Elvis · both eyes blue · Variant known, this cat untested · also in its ancestry: Pillowtalk-Foreigner

Under the variant field this directory proposes, this cat would read DBE 164p. The variant is attributed to this animal from the record rather than from a result on it. 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. BigBoots Big T, MCO d 22 68
2. BigBoots Dirty Dodge, MCO as 09 68, the sire of BigBoots Big T
3. Joyfield's Avril, MCO fs 09 68, the dam of BigBoots Dirty Dodge
4. Rociri Elvis, MCO e 09 68, the sire of Joyfield's Avril. DBE-RE, adopted by this survey; a founder of this survey

That is 3 recorded parent links, and the animal at the end of it carries a variant this survey has adopted, but has not itself been tested. 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.

How the variant was established

LINEAGE GENOTYPED, DBE-RE. NOT TESTED. DBE-RE IS FIXED BY A DNA GENOTYPE IN THIS CAT'S OFFSPRING. BigBoots Belle Azure carries DBE-RE and a dominant allele must come from a parent. No other recorded parent of that cat shows a blue or odd eye, so this cat transmitted it. The deduction is certain and no sample of this animal exists.

Computed from the recorded parentage at every build. It sits above a traced descent and below a laboratory result, and it is withheld wherever a second variant sits in the ancestry.

What is flagged on this tree

1. 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
2. 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
3. JOYFIELD'S AVRIL. CODED 68 BY PAWPEDS AND MCO fs 09 BY FELIS DANICA. She stands as the dam on the Felis Danica record for BigBoots Pommeline, where she is given as '17.MCO3131.3 Joyfield's Avril MCO fs 09'. The 68 is on the PawPeds pedigree and not on the Danish one. SHE IS ONE OF THE TWO DAUGHTERS THROUGH WHICH ROCIRI'S ELVIS REACHES THE BIGBOOTS PREFIX | ON THE GENOTYPED BIGBOOTS DESCENT. This animal stands in the dam line of BelleAyr Pluto, who is genotyped DBE-RE, between Joyfield's Avril and BigBoots Belle Azure. FOUR CONSECUTIVE GENERATIONS CODED 68 ENDING IN A TESTED CAT, which is the strongest support this register holds for reading the BigBoots 68 as one variant descending from Rociri's Elvis | SHE IS WHERE THE 68 AND THE 69 AND THE GENOTYPE ALL MEET. She is coded 68 and out of Rociri's Elvis, coded 68. HER DAUGHTER BIGBOOTS COCO CHANEL IS CODED 69 BY A SIRE WITH NO CODE ANYWHERE ON HIS SIDE. HER OTHER DESCENT, THROUGH BIGBOOTS DIRTY DODGE AND BIGBOOTS BIG T AND BIGBOOTS BELLE AZURE, ENDS IN BELLEAYR PLUTO, GENOTYPED DBE-RE. One dam, a 69 on one branch and a laboratory-confirmed DBE-RE on the other
4. BIGBOOTS DIRTY DODGE. CODED 68 BY PAWPEDS AND BY THE CATTERY, AND MCO as 09 BY TWO NATIONAL REGISTRIES. He appears as the sire on the Norwegian record for Bigboots Autumn and on the Finnish record for BigBoots Autumn Storm, and both give him as 'Bigboots Dirty Dodge MCO as 09', registration [registration number held privately], WITH NO 68. He is the sire of the BigBoots 68 line on these sheets, and the code that makes him one is carried by one database of the three | ON THE GENOTYPED BIGBOOTS DESCENT. This animal stands in the dam line of BelleAyr Pluto, who is genotyped DBE-RE, between Joyfield's Avril and BigBoots Belle Azure. FOUR CONSECUTIVE GENERATIONS CODED 68 ENDING IN A TESTED CAT, which is the strongest support this register holds for reading the BigBoots 68 as one variant descending from Rociri's Elvis
5. BIGBOOTS BIG T. ON THE GENOTYPED BIGBOOTS DESCENT. This animal stands in the dam line of BelleAyr Pluto, who is genotyped DBE-RE, between Joyfield's Avril and BigBoots Belle Azure. FOUR CONSECUTIVE GENERATIONS CODED 68 ENDING IN A TESTED CAT, which is the strongest support this register holds for reading the BigBoots 68 as one variant descending from Rociri's Elvis

In the register

• Parents: BigBoots Dirty Dodge, Coonieshouse Akina P
• Offspring recorded in this register; a cat may have others: BigBoots Belle Azure

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.
