Genetic indicators of the litter
All three figures are recalculated for the number of generations selected.
COI — inbreeding
0%
No common ancestor over 5 generations.
AVK — distinct ancestors
83.9%
52 distinct ancestors out of 62 possible. Among known ancestors only: 100%.
Pedigree completeness
83.9%
10 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.
