^aTrue breeding values were estimated for individuals from generation 50, for performance in generation 50 and the three previous generations based on the genotypes of the individuals in generation 50 and the statistical additive effects of each of those generations
^bResults are shown as averages across the 20 replicates with their corresponding standard errors of the mean between brackets
