| Stochastic simulations were used to compare genetic progress and inbreeding depending on whether full sib matings were allowed or not when applying individual selection. Fifteen selection cycles were considered, using a single pair mating design. Two levels of heritability (h(2)) were studied (0.1; 0.5) as well as four different proportions of selected animals (2, 5, 10 and 20%), four population sizes (1000, 2,000, 4,000 and 10,000 candidates) and two levels of inbreeding depression (0 and 5% decrease of phenotype for 10% increase in inbreeding). Fifty replicates were generated for each set of parameters. The simulations revealed that avoiding full sib matings became less and less relevant as population size and proportion of selected animals increased and... |
