  1. Investigated parameters were: accumulated inbreeding (F7), accumulated genetic merit (G7), sum of squared long term genetic contributions of founders (∑r2/4), difference in additive genetic variance component in 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), deviation from H-W equilibrium (α7) at generation seven. Standard errors ranged between 0.0004 and 0.0030 for F7, 0.11 and 0.13 for G7, 0.0001 and 0.0005 for ∑r2/4.
