  1. Genetic gain (ΔG5), accuracy (acc5), rate of inbreeding (ΔF5) and genetic variance (vg5) in generation 5 for schemes with different numbers of candidates (Ncand = 3000 or 6000), tested sibs (Ntested = 3000 or 6000) and families (Nfamilies = 100 or 200) and heritability levels (0.1 or 0.4). EVERY-GEN testing strategy was used.
  2. 1h2 = 0.4, Ncand = 3000, Ntested = 3000, Nfamilies = 100
