  1. Investigated parameters were: accumulated inbreeding (F7), accumulated genetic merit (G7), sum of squared long term genetic contributions (∑r2/4), difference in additive genetic variance component as a percentage (ΔVA), average number of selected trees per generation (Nsel), average number of crosses per generation (Ncro), average number of full-sibs/family in each generation (Nful), amount of deviation from Hardy-Weinberg equilibrium (α7) at generation seven. Standard errors ranged between 0.0001 and 0.0016 for F7, 0.08 and 0.09 for G7, 0.00004 and 0.00024 for ∑r2/4.
