Genetic indicators

All three figures are recalculated for the number of generations selected.

COI — inbreeding

10.74%

Moderate. Common ancestors: Tochini Go Izumi Shigeru Of Akita, Babagoma Go Ichinoseki, Seagusa Go Mitane Go, Noro Gomame Go, Aka Go Nyuui and 4 more.

AVK — distinct ancestors

30.6%

19 distinct ancestors out of 62 possible. Among known ancestors only: 52.8%.

Pedigree completeness

58.1%

26 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 + F_A), 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.
