How this cat is connected to the trait

1. Ermine Trace Xrustal, BSH ny 11 33
2. Ermine Trace Nadeya, BSH ns 09 11 68, the dam of Ermine Trace Xrustal. 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.

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 Nadeya, Ermine Trace Qorall, GIC Andy vom Wahrberg, GIC Marvellous Golden Radetzky, IC Goldfever's Golden Mikka, Jadwiga's Silver Classic Touch, Jaki Ami Sissy Crazy Blue, Leonardo De Cassis, Marvellous Golden Dream, Sonnyboy Zur Porta Westfalica, Tjarden von Felden. 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 the pedigree implies

POSSIBLE CARRIER BY DESCENT. the Igor line, no variant identified, through Jaki Ami Sissy Crazy Blue, Leonardo De Cassis; the Nadeya line, no variant identified, through CH Carajan zur Sternebucht, CH Du Blue D'or Argentin Nuance's Golden, CH Idefix von Konradsburg

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.

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 QORALL. THE HIGHEST COEFFICIENTS OF INBREEDING IN THIS REGISTER, AND THE DOUBLED CAT CARRIES NO EYE CODE. Smile Ermine Trace returns 25.0 PER CENT on twenty-two unique ancestors of thirty, and Tanatos Ermine Trace returns 20.3 PER CENT on nineteen of thirty. In both cases ERMINE TRACE QORALL, BSH ny 12, STANDS TWICE: he is the sire of Smile and also the sire of Smile's dam Zarafina, which is a father to daughter mating; and he is the sire of Tanatos's sire Xrustal AND the sire of Tanatos's dam Zarafina, which makes those two half-siblings. ERMINE TRACE NADEYA, THE FOUNDER, ALSO STANDS TWICE ON THE TANATOS SHEET. THE REGISTER RECORDS THIS AS A FACT ABOUT THE MATINGS AND NOT AS A JUDGEMENT. What it shows is that the coded cats of this line are being produced by doubling back onto the line, WHICH IS WHAT A BREEDER DOES TO FIX A TRAIT, and that the animal doubled is one that carries no eye code at all
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 XRUSTAL. THE CODE GOES 68, 69, 68 AND CROSSES INTO A SECOND BREED. Unreal ZouWu Ermine Trace is BLH ny 11 68, A BRITISH LONGHAIR, out of URBI ET ORBI ERMINE TRACE, BSH ns 09 11 69, out of ERMINE TRACE XRUSTAL and ERMINE TRACE NADEYA, BSH ns 09 11 68. HIS DAM MANILA ERMINE TRACE IS BLH ny 12 WITH NO EYE CODE, and neither she nor any of the fourteen Boon animals above her carries one. THE 68 ON HIM CAME FROM A 69 SIRE AND FROM NOWHERE ELSE | HE CARRIES NO WHITE AT ALL, ny 11 being black golden shaded, WHERE HIS SIRE CARRIES 09. The white drops out of the code in one generation and the eye does not | ERMINE TRACE XRUSTAL NOW HAS FOUR CODED DESCENDANTS AND HE WAS PLACED AS NOT CARRYING THE GENE: Lemniscata 64, Tanatos 68, Urbi et Orbi 69, and through Urbi et Orbi this grandson at 68 in another breed

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.

Line-traced descent from a named founder is stated by the source

In the register

• Parents: Ermine Trace Qorall, Ermine Trace Nadeya
• Offspring recorded in this register; a cat may have others: Ermine Trace Lemniscata, Tanatos Ermine Trace, Urbi et Orbi Ermine Trace

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.
