The results presented are means of the 100 replicates; standard deviations of the 100 replicates ranged from 0.05 to 0.07; ¹see Table 1 for a description of the different breeding scenarios;

²1:1 Breeding goal = $\frac{1}{\sqrt{2}}$ Breeding Value for trait 1 + $\frac{1}{\sqrt{2}}$ Breeding value for trait 2;

1:3 Breeding goal = $\frac{1}{\sqrt{10}}$ Breeding Value for trait 1 + $\frac{3}{\sqrt{10}}$ Breeding value for trait 2; within a column: all means differ (p < 0.01) except means with common superscripts.
