Cumulative response for breed average and heterosis in crossbreds. Cumulative response for breed average (red crosses) and heterosis in crossbreds (blue dots) was computed from scenario 1, with large V_D and allowing overdominance, when there was one chromosome, 100 QTL and 1000 SNPs; the plotted cumulative responses are means from 1600 replicates, standardized by the phenotypic standard deviation of crossbreds in generation 0: (a) cumulative response using the dominance model (y-axis) plotted against response using the additive model (x-axis), (b) cumulative response using the dominance model against response using BSAM and (c) cumulative response using BSAM against the additive model; the broken line is y=x.
