Additional file 2: Table S2. SNPs with significant dominance effects of PL. This table provides test results for all significant dominance effects. ‘Allele-1’ is the nucleotide of allele ‘1’, and ‘Allele-2’ is the nucleotide of allele ‘2’. ‘Effect’ is the dominance effect of the SNP as the difference between the heterozygous dominance value and the average of the two homozygous dominance values (Eq. (11)). ‘Yij’ is the genotypic average of phenotypic values of cows with the ij genotype (i,j = 1,2). ‘dl++’ is the genotype with the highest dominance value. ‘dv++’ is the dominance value of the ‘dl++’ genotype. ‘dl+–’ is the genotype with the second highest dominance value. ‘dv+–’ is the dominance value of the ‘dl+–’ genotype. ‘dl–’ is the genotype with the lowest dominance value. ‘dv–’ is the dominance value of the ‘dl–’ genotype. ‘f_dl++’ is the frequency of the dl++ genotype. ‘f_dl+–’ is the frequency of the ‘dl + –’ genotype. ‘f_ dl–’ is the frequency of the ‘dl–' genotype. ‘ae+’ is the allelic effect of the positive allele (Eq. (9)). ‘ae–’ is the allelic effect of the negative allele (Eq. (9)). ‘f_al+’ is the frequency of the positive allele. ‘f_al-’ is the frequency of the negative allele. The 12 SNPs on the sheet ‘12SNPs’ are recommended for heifer culling.
