High Genetic Diversity (AVK ≥ 85%): Excellent outcrossing with minimal ancestor loss. Strong gene pool vitality.

Understanding AVK vs. COI in Dog Breeding

•

What AVK Measures: AVK (Ahnverlustkoeffizient) measures the percentage of unique individuals in a pedigree. 100% means every single ancestor is distinct.

•

Difference from COI: Wright's COI measures the probability of inheriting identical gene alleles from common ancestors. AVK evaluates the overall variety in the ancestral tree.

•

Breeding Goal: Ideal purebred breeding balances an AVK above 80% with a 5-generation COI below 6.25% to prevent genetic bottlenecks.
