Genetic indicators
All three figures are recalculated for the number of generations selected.
COI — inbreeding
14.06%
High. Common ancestors: Kakutora Sumitora Go Mogami Hoshikawa, Bushoumaru Go Enshuunada Oukasou, Hakuju Go Gassan Shiunsou, Tsunatora Go Megumi, Hana Go Mizuhosou and 11 more.
AVK — distinct ancestors
59.7%
37 distinct ancestors out of 62 possible. Among known ancestors only: 68.5%.
Pedigree completeness
87.1%
8 empty slots. The AVK takes them into account, so read both figures together.
How these figures are calculated
COI — Wright's formula: F = Σ (½)n₁+n₂+1 × (1 + FA), summed over every path through a common ancestor A. The number of generations must be fixed for two dogs to be comparable: a more complete pedigree mechanically raises the figure.
AVK — distinct ancestors divided by the theoretical number of ancestors. Over 5 generations there are 62 possible slots. 100% means no ancestor appears twice.
Completeness — the share of slots actually filled in. The AVK is misleading without it: a half-empty pedigree shows a low AVK even with no inbreeding at all, simply because data is missing.
