  • a Nomenclature of Parkin et al. (1995)

  • b Percentage of the variance explained by a locus when added last to the model.

  • c R, D, and Tindicate the recurrent parent, donor parent, and Topas alleles at the locus, respectively. RR→DD represents the substitution of the RR genotype by the DD genotype (more details are provided in materials and methods). When effects differed significantly in each background (P < 0.01), estimates of allele substitution are reported in brackets for each background separately, [EstimateMarnoobackground, EstimateWestarbackground]. Otherwise, a pooled estimate is given.

  • d Estimates the interaction as difference between the effect of the joint substitution of alleles at both loci and the sum of the effect of allele substitution at each locus separately.
