Azia Ermine Trace

prefix Ermine Trace · British Longhair · line: Nadeya · both eyes blue · Variant known, this cat untested · also in its ancestry: Igor

Under the variant field this directory proposes, this cat would read no field at all, which the scheme calls unknown. Two causes of a pale eye stand on one record and nothing separates them. The scheme leaves this cat unknown rather than coding it either way. 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. Azia Ermine Trace, BLH ns 12 33 68
2. Ermine Trace Enya, BSH ns 11 69, the dam of Azia Ermine Trace
3. Ermine Trace Nadeya, BSH ns 09 11 68, the dam of Ermine Trace Enya. a founder of this survey; no variant has ever been identified in this line

That is 2 recorded parent links, 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.

Three or more variants could be present in this cat

DBE-ALT and Igor, unidentified and Nadeya, unidentified. MORE THAN ONE VARIANT COULD BE PRESENT IN THIS CAT: DBE-ALT, Igor, unidentified, Nadeya, unidentified. It is not established that any of them is, and it is not established that two are. A dominant allele comes from a parent, and this cat's recorded ancestry carries an attribution of each. The attributions above it are on CH Carajan zur Sternebucht, CH Du Blue D'or Argentin Nuance's Golden, CH Idefix von Konradsburg, CH Jadwiga's Golden Undina, CH Kandy von Romero, CH Lady Di von Wahrberg, CH Marvellous Silver Ramzes II, CH Ondra von Ursus Minor, EC Golden-Willow von Wahrberg, EC Maurice vom Wahrberg, Ermine Trace Barkhat, Ermine Trace Enya, Ermine Trace Jeana, Ermine Trace Kashemir, Ermine Trace Lazurit, Ermine Trace Nadeya, GIC Andy vom Wahrberg, GIC Emilio vom Rosentor, GIC Marvellous Golden Radetzky, IC Freedom zur Raeuberhoehle, IC Goldfever's Golden Mikka, IC Marvellous Miss Goldfever, IC Mels van Wierinxveste, Jadwiga's Silver Classic Touch, Jaki Ami Sissy Crazy Blue, Leonardo De Cassis, Marvellous Golden Dream, Marvellous Golden Samba, Shakira, Sonnyboy Zur Porta Westfalica, Sweet Heartbreaker's Love Me Tender, Tjarden von Felden, Zaremba. A CAT HOLDING TWO IS A COMPOUND HETEROZYGOTE, which this survey records as the state associated with deaf and dead kittens, and NOTHING BUT A TEST DISTINGUISHES ONE FROM TWO.

Computed from the recorded parentage at every build, counting both the variants this survey adopts and the ones it records a source claiming and does not adopt. IT IS AN UPPER BOUND AND NOT A FINDING: it says what could be here, never what is.

What is flagged on this tree

1. SCHOENWEG MONA LISA. Query. THE CHART RAISES A QUESTION ABOUT THIS CAT'S BLUE EYE AND DOES NOT ANSWER IT. Chart C13 annotates this animal 'Chinchilla-point with very blue eyes, possibly due to a blue-eye gene rather than the colourpoint gene'. A colourpoint cat is blue-eyed through the C locus, so a blue eye on a pointed cat is normally accounted for and carries no evidence of a dominant variant. THE COMPILER'S POINT IS THAT THE DEPTH OF COLOUR IS UNUSUAL, which is an observation and not a test. It is recorded as the query it is and no variant is adopted
2. SCHOENWEG TEODORO. Query. THE CHART RAISES A QUESTION ABOUT THIS CAT'S BLUE EYE AND DOES NOT ANSWER IT. Chart C13 annotates this animal 'Chinchilla-point with very blue eyes, possibly due to a blue-eye gene rather than the colourpoint gene'. A colourpoint cat is blue-eyed through the C locus, so a blue eye on a pointed cat is normally accounted for and carries no evidence of a dominant variant. THE COMPILER'S POINT IS THAT THE DEPTH OF COLOUR IS UNUSUAL, which is an observation and not a test. It is recorded as the query it is and no variant is adopted
3. ERMINE TRACE LAZURIT. Outbred. THIRTY ANCESTORS OF THIRTY POSSIBLE AND ALL THIRTY UNIQUE, coefficient of inbreeding 0.0 per cent on four complete generations. THE DOUBLING SEEN LOWER IN THIS LINE DOES NOT COME FROM HIM: his son Ermine Trace Jantar returns 6.25 per cent, and the repeated positions there enter through the dam, Ermine Trace Cherry, who is also out of Lemurcat Xantares | Code. HE IS REGISTERED 67, THE POINTED CODE, AND THE CHART DRAWS HIM WITH TWO BLUE EYE ICONS. Code 67 attributes a blue eye to the Siamese gene. Both statements are recorded and neither is preferred
4. ERMINE TRACE NADEYA. Attribution. THE CHART NAMES THIS LINE'S VARIANT AND THIS REGISTER HAD IT AS UNIDENTIFIED. Genealogy C13 is headed 'NANOTIGR BLUE-EYED BRITISH SHORTHAIRS, DBE-ALT' and writes DBE-ALT in red beside Oliver, beside Amelia Nanotigr and beside ERMINE TRACE NADEYA, who is the foundation cat of the Ermine Trace dominant blue-eyed line. THE ERMINE TRACE AND NANOTIGR CATS ARE THEREFORE ATTRIBUTED DBE-ALT BY THEIR OWN CHART. It is an attribution and not a test: no Ermine Trace cat holds a laboratory result, and the only result ever held for Nadeya was a colourpoint test at the C locus, which this register corrected on 17 August 2026. THE VARIANT IS RECORDED AS CLAIMED AND NOT ADOPTED, which is what the variant_claimed field is for, and the line stops being counted as a variant of its own
5. ERMINE TRACE ENYA. 68 AND 69 ALTERNATING DOWN A SINGLE-SOURCE DESCENT, IN A SECOND BREED. On these five sheets the line runs ERMINE TRACE NADEYA, BSH ns 09 11 68, to ERMINE TRACE ENYA, BSH ns 11 69, to ERMINE TRACE SAPPHIRE, BSH ns 09 12 68, to ERMINE TRACE JANTAR, BSH ny 09 25 68, to NEFERTITI ERMINE TRACE, BSH ny 25 69. FIVE GENERATIONS AND THE CODE GOES 68, 69, 68, 68, 69. The second branch does the same: Enya to ZARAFINA ERMINE TRACE, BSH ny 11 68, to FABERGE ERMINE TRACE, BSH ny 09 11 68. EVERY SIRE BROUGHT IN AGAINST THESE DAMS CARRIES NO EYE CODE AT ALL: Ermine Trace Kashemir BSH ns 11, Lusy-Mur Dionis BSH ay 11, Ermine Trace Qorall BSH ny 12, and no animal above any of them carries one either. THERE IS NO SECOND SOURCE ON THESE SHEETS. This is the Arst Venezia result reached again in a different breed and a different country: A SINGLE VARIANT SEGREGATING IN ONE LINE IS SUFFICIENT TO PRODUCE BOTH CODES. NOTHING IN THIS MATERIAL HAS BEEN GENOTYPED

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.

EMS code

BLH ns 12 33 68

The code read out

British Longhair; black silver; shell or tipped, colourpoint; dominant blue eyes, written in the 68 series

The description held

coded 68 in the PawPeds dominant blue eye listing. NO PEDIGREE, PARENTS OR VARIANT ARE GIVEN THERE, so nothing is traced and nothing is adopted. POINTING NOTE 27 AUGUST 2026: HER OWN CODE CARRIES 33, COLOURPOINT, AND THE POINTED GENE IS AN ORDINARY CAUSE OF A BLUE EYE. The registry has coded her 33 and 68 on the same line, so two causes of a pale eye stand on one animal and the record cannot separate them. She is not read as evidence either way

Evidence grade

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.
