Accuracy of selection of the SIB_TRAIT (acc_{SIB_TRAIT}), rates of inbreeding (ΔF) and genetic gain of the SIB_TRAIT (ΔG_{SIB_TRAIT}) and GROWTH (ΔG_GROWTH) in generation G5 with different numbers of families per group (Nfampergroup), test individuals (Ntest) and markers (Nmarkers). The heritability of the SIB_TRAIT was 0.4, number of families (Nfam) was 100 and the number of preselected candidates (Npresel) was 1000. s.e. of ΔF was between 0.001 and 0.002
