Significance (P), allele substitution effect (Effect) for the named allele of each SNP, its standard error (SE) and percentage of additive variance (%Va) explained by 3 SNP genotypes in Tex11 and 1 SNP in AR on Scrotal Circumference (SC) at 12, 18 and 24 months of age and on the percentage of normal sperm (PNS) at 18 and 24 months of age.
