  1. Investigated parameters were: accumulated inbreeding (F), accumulated genetic merit (G), sum of squared long term genetic contributions of founders (∑r2/4), reduction in additive genetic variance component (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), deviation from H-W equilibrium (α7) at generation seven. Standard errors ranged between 0.0002 and 0.0014 for F7, 0.07 and 0.10 for G7, 0.00005 and 0.00008 for ∑r2/4.
