Extreme male reproductive skew limits effective population size in American Standardbred horses

2026-01-03

Abstract excerpt

Standardbred horses are widely used for harness racing in North America, Europe, Australia, and New Zealand. In the U.S., two gaits (Pacers and Trotters) are genetically differentiated at a level typical for different horse breeds. We used the complete pedigree for all registered American Standardbred foals born 1970-2014 (>200K Trotters and >500K Pacers) to calculate annual and lifetime reproductive skew and its...
