h²: heritability of the trait; n_R: number of individuals in RP; n_V: number of individuals in VP; n_L and n_H are the average number individuals in L and H groups over replicates, respectively; $R_L^2$ and $R_H^2$ are the predictive accuracies in L and H groups, respectively; ${\overline{UP}}_L$ and ${\overline{UP}}_H$ are the mean of the average UP at each replicate for L and H, respectively.
