Total number of SNPs with significant ( P  < 10 ⁻⁴ ) dominance effects, number of SNPs with positive (+ve) and negative (−ve) dominance effects in the discovery population, number of SNPs tested for validation of dominance effects (Nb tested), and percentage of SNPs with positive and negative dominance effects that had an effect in the same direction in the validation population for each trait

¹Trait abbreviations are in Table 1; ²percentage of significant SNPs (%) that had an effect in the same direction in the validation population: ^* those that significantly differ from the expected number of SNPs at P < 0.05; ^**those that significantly differ from the expected number of SNPs at P < 0.01; and ^***those that significantly differ from the expected number of SNPs at P < 0.001.
