Grand Duke Azure Dream

British Shorthair · line: Igor · both eyes blue · Published line, tested against the known variants and carrying none

Under the variant field this directory proposes, this cat would read DBE 161 x1p. 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

1. Grand Duke Azure Dream, BSH a 01 61
2. Chilly Aquamarine Azure Dream, BRI e 03 61, the sire of Grand Duke Azure Dream
3. Igor, BSH n 02 61, the sire of Chilly Aquamarine Azure Dream. 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.

What is flagged on this tree

1. IGOR, GIVEN ON THE PAWPEDS PEDIGREE AS IGOR AZURE DREAM AND ON THE BREEDER CHARTS SIMPLY AS IGOR. THE FOUNDER OF THE LINE THE BREEDER CHARTS CALL IGOR, and the head of every chart headed 'line descended from Altai gene Igor'. HE IS NOT THE ALTAI GENE MALE HIMSELF: the charts draw a starred, unnamed animal above him, described as 'BSH x Altai registered as BSH?', and that animal is not entered here because no document names it. TWO COAT READINGS STAND ON HIM, BSH a from the chart crops and BSH n 02 61 from the registry pedigree, and neither is discarded; his son Amur Dream is BRI n 01, which is consistent with the second. Folded from igr-a01 and igr-b07 on 28 August 2026 by parentage: same mate, Onyx Magic Smile, and the same two offspring. S_FOLD_155
2. IGOR, GIVEN ON THE PAWPEDS PEDIGREE AS IGOR AZURE DREAM AND ON THE BREEDER CHARTS SIMPLY AS IGOR. Eye and coat, HELD APART FROM THE DIAGNOSTIC. This cat is blue-eyed in both eyes and is not dominant white and not colourpointed, but its white code is van or harlequin. VERY HIGH WHITE CAN PRODUCE BILATERAL BLUE ON ITS OWN, which a traditional bicolour cannot, so the coat is NOT excluded here and this cat is not counted in the diagnostic. The distinction matters most at the founders: it is where this register would otherwise overclaim.
3. ONYX MAGIC SMILE. ONE CAT ON FOUR RECORDS, AND THE SPLIT WAS HIDING A FULL-SISTER RELATIONSHIP. ONYX MAGIC SMILE APPEARED AS igr-a21, igs-19, igr-b09 AND sqx-92. Three of the four name the same parents in words, EC LORD CREME JONAS VOM WERNERWALD BY ICE LADY V PEO'S CAT, and the fourth records that Kittystar Brilliant's certificate gives her a different ancestry, WHICH IS ITSELF EVIDENCE AND IS KEPT | WHAT THE SPLIT COST. ALESTA AZURE DREAM hung on one copy and CHILLY AQUAMARINE AZURE DREAM on another, AND BOTH ARE OUT OF IGOR AZURE DREAM. THE TWO ARE FULL SISTERS OUT OF ONE MATING AND THE REGISTER COULD NOT SEE IT. Alesta is BSH a 09 with NO EYE CODE and is the dam of KOOPER SUPERQUEEN, 68. Chilly Aquamarine is BRI e 03 61, CODED, with three recorded offspring running on through the Azure Dream prefix. THE SUPERQUEEN 68 AND THE AZURE DREAM 61 SIT ON TWO FULL SISTERS OUT OF IGOR AZURE DREAM BY ONYX MAGIC SMILE | AND WHAT THAT MEANS FOR THE UNCODED SISTER. Alesta carries no eye code at all and her son is 68. Her full sister is coded 61 and 03, a bicolour, so the coat rule sets the sister aside as evidence. ALESTA HERSELF IS 09, WHICH IS ALSO THE EXCLUDED TIER. NEITHER SISTER CAN BE USED TO SHOW ANYTHING, AND BETWEEN THEM THEY STAND ABOVE A 68 AND A 61 | HOW THE MERGE WAS DONE. This register lost nine ALT by CEL crossings once before because a sweep moved the links POINTING AT a duplicate and left the duplicate's OWN PARENTS in place. HERE BOTH ENDS WERE MOVED: every child repointed to the canonical record and every duplicate stripped of its own parents, so no phantom branch survives. THE DUPLICATE RECORDS THEMSELVES ARE KEPT, because each is a separate document and this register audits by document
4. CHILLY AQUAMARINE AZURE DREAM. ONE CAT ON FOUR RECORDS, AND THE SPLIT WAS HIDING A FULL-SISTER RELATIONSHIP. ONYX MAGIC SMILE APPEARED AS igr-a21, igs-19, igr-b09 AND sqx-92. Three of the four name the same parents in words, EC LORD CREME JONAS VOM WERNERWALD BY ICE LADY V PEO'S CAT, and the fourth records that Kittystar Brilliant's certificate gives her a different ancestry, WHICH IS ITSELF EVIDENCE AND IS KEPT | WHAT THE SPLIT COST. ALESTA AZURE DREAM hung on one copy and CHILLY AQUAMARINE AZURE DREAM on another, AND BOTH ARE OUT OF IGOR AZURE DREAM. THE TWO ARE FULL SISTERS OUT OF ONE MATING AND THE REGISTER COULD NOT SEE IT. Alesta is BSH a 09 with NO EYE CODE and is the dam of KOOPER SUPERQUEEN, 68. Chilly Aquamarine is BRI e 03 61, CODED, with three recorded offspring running on through the Azure Dream prefix.

5. CHILLY AQUAMARINE AZURE DREAM. Eye and coat, A DETERMINATION AND NOT A QUERY. This cat is blue-eyed in both eyes, carries a bicolour or locket white code, is not dominant white and is not colourpointed. THE CLASSIC WHITE SPOTTING GENE COVERS AN EYE WHERE THE WHITE HAPPENS TO FALL, WHICH GIVES AN ODD EYE AND NOT TWO BLUE ONES, so the coat does not account for this and a dominant blue eye is present in the line. IT IS NOT THE KIT ODD-EYE CASE. Its registry has entered no dominant eye code on it. WHICH VARIANT IS NOT DEDUCIBLE FROM A COAT CODE and none is adopted.
6. LE CHAT EN VELOURS MADONNA. Eye and coat, A DETERMINATION AND NOT A QUERY. This cat is blue-eyed in both eyes, carries a bicolour or locket white code, is not dominant white and is not colourpointed. THE CLASSIC WHITE SPOTTING GENE COVERS AN EYE WHERE THE WHITE HAPPENS TO FALL, WHICH GIVES AN ODD EYE AND NOT TWO BLUE ONES, so the coat does not account for this and a dominant blue eye is present in the line. IT IS NOT THE KIT ODD-EYE CASE. Its registry has entered no dominant eye code on it. WHICH VARIANT IS NOT DEDUCIBLE FROM A COAT CODE and none is adopted.
7. GRAND DUKE AZURE DREAM. Eye and coat, HELD APART FROM THE DIAGNOSTIC. This cat is blue-eyed in both eyes and is not dominant white and not colourpointed, but its white code is van or harlequin. VERY HIGH WHITE CAN PRODUCE BILATERAL BLUE ON ITS OWN, which a traditional bicolour cannot, so the coat is NOT excluded here and this cat is not counted in the diagnostic. The distinction matters most at the founders: it is where this register would otherwise overclaim.

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.
