Ermine Trace Enya
prefix Ermine Trace · British Shorthair · line: Nadeya · one blue eye · Variant known, this cat untested
Under the variant field this directory proposes, this cat would read DBE 161 x2p. A carrier of a variant nobody has sequenced, on a line this proposal gives a suffix to. 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
Ermine Trace Enya, BSH ns 11 69
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 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.

More than one variant could be present in this cat
DBE-ALT and Nadeya, unidentified. MORE THAN ONE VARIANT COULD BE PRESENT IN THIS CAT: DBE-ALT, 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 Ermine Trace Kashemir, Ermine Trace Nadeya. 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
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
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
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
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
BSH ns 11 69
The code read out
British Shorthair; black silver; shaded; dominant odd eyes, written in the 68 series
The description held
NO WHITE CODE OF ANY KIND. The 11 and 12 in these codes are shaded and shell, which are tipping and not white spotting, and 25 is ticked tabby. THERE IS NO w, NO 01, 02, 03, 08 OR 09, AND NO 33 COLOURPOINT. A blue or odd eye on this animal is therefore not attributable to dominant white, to white spotting or to the pointed gene, and the coat excludes every alternative the register separates. SHE IS THE HINGE OF THIS LINE. Her dam Ermine Trace Nadeya is coded 68, she is coded 69, and her sons Ermine Trace Sapphire and her granddaughter Zarafina Ermine Trace are coded 68 again. HER SIRE ERMINE TRACE KASHEMIR IS BSH ns 11 WITH NO EYE CODE, and neither Schoenweg Teodoro nor Kamilla Silver County above him carries one, so the 69 on her cannot be attributed to a second line entering through him

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.
