Illustration of the computation of EMBV for a heterozygous selection candidate. A (conceptually) infinite population of gametes is generated in silico from the candidate by simulating meiosis events. The corresponding doubled haploid (DH) lines are evaluated for their GEBVs, yielding a distribution of GEBVs (blue curve). The candidate’s GEBV corresponds to the mean GEBV of the DH lines. The EMBV is defined as the expected value of the maximum GEBV of a random sample of DH lines of size $N_G,$ where $N_G$ is the expected number of gametes the candidate will contribute to the next generation.
