  1. 1/Genetic distances according to Blair et al. (2003) with mapping of BMd8 from Ochoa et al. (2006). Significance of LD evaluated with Fisher's exact tests, P-values: *<P = 0.05; **<0.01; ***<0.001; ns, not-significant, NA = not applicable, no LD test applied to marker combinations where one marker had no allelic diversity in the subgroup
