¹In the region UMNP891-UMNP93, 4 microsatellite markers (UMNP891, MCSE347J6, SW1522, UMNP93) and 7 SNPs were genotyped. For simplicity, we indicated the haplotypes with only microsatellites alleles because they reveal all individual haplotypes formed by all markers analysed on these animals.
²Each sub-family consists of F₁ full-sisters.
³The θ of the F₁ full-sisters within the first subfamily are highlighted in bold because they showed the largest difference in θ (P = 0.0026).
