Table 4 Mean J-factor covariates of the 100 replicates, estimated for the three breeds with animals phenotyped for body weight at 7 and 35 days (BW7 and BW35)

From: Validation with single-step SNPBLUP shows that evaluations can continue using a single mean of genotyped individuals, even with multiple breeds
