Summary. The transmission ratios of alleles at 12 protein marker loci were computed individually for American Standardbred stallions in a genealogy of 5392 phenotyped horses. Over all loci there was significant gene transmission distortion for trotting stallions (p=0.0019) but not for pacing stallions (p=0.99). The transmission distortion was due to sire‐specific effects (p=0.0024) and not to increased transmission of one or the other allele of a given heterozygous genotype (p=0.21). Individual‐specific, non‐random transmission of homologous chromosomes may provide a mechanism for selection to operate without requiring differential fitness for specific alleles or genotypes in the population as a whole.
