Cumulative response to genomic selection with ten chromosomes. Cumulative response to GS was computed using the dominance model, BSAM and the additive model in the four scenarios, when there were ten chromosomes, 1000 QTL and 10 000 SNPs; the plotted cumulative responses are means from 1600 replicates, standardized by the phenotypic standard deviation of crossbreds in generation 0: (a) results from scenario 1, where V _D was large with overdominance, (b) results from scenario 2, where V _D was realistic with overdominance, (c) results from scenario 3, where V _D was realistic without overdominance and (d) results from scenario 4, where dominance was absent.
