  1. Rates of inbreeding in percentage (ΔF) and genetic gain in genetic standard deviation units (ΔG) generated per generation when ns = 25, nd = 25 and h2 = 1 for schemes where parent selection is on BLUP EBV using sib information (BLUP/SIB); for schemes where parent selection is on GS EBV using sib information (GS/SIB); RAND: random; MC: minimum coancestry; MCAC: minimizing covariance of ancestral contributions mating; standard errors of means of 100 replicates of genetic gain were less than 0.21% and of rates of inbreeding were less than 0.38%
