Genetic indicators

COI — inbreeding

12.5%

High. Common ancestor: Inverbrae Alexandra.

AVK — distinct ancestors

21%

13 distinct ancestors out of 62 possible. Among known ancestors only: 81.3%.

Pedigree completeness

25.8%

46 empty slots. The AVK takes them into account, so read both figures together.

Common ancestors and how they connect 1

Over 5 generations: each ancestor found on both the sire's and the dam's side, and what it adds to the COI.

Ancestor	Sire's side	Dam's side	Share of the COI

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.
