↵^{a} For null hypothesis of zero chromosome substitution effect for sire.
↵^{b} Thresholds for significant sire QTL estimates at P < 0.05 and P < 0.01 are 0.83 and 1.10 genetic standard deviation units for heritability = 0.25 and equal to 0.47 and 0.62 genetic standard deviation units for heritability = 0.70.
