Figure 1

Accuracy of genomic EBV for reference populations with different progeny group sizes. Different lines indicate different progeny group sizes; PG = genotyped individuals in the reference population have an own performance records (same individuals phenotyped and genotyped); when the progeny group size is, e.g., 20, the number of genotyped individuals in the reference population (n _P ) equals the total number of phenotypes divided by the size of the progeny group; accuracy $r_{g\hat{g}}$ is calculated from Equations 2a-d, for N_E = 100, L = 30, and h² = 0.3.
