| Mating plans have been used in animal breeding for the purpose of profit from dominance genetic effects. With the advent of genomic selection these methods should be revisited. The objective of this study is to quantify the efficiency of mating allocation under a whole genome evaluation scenario in terms of genetic response. Two strategies of selection, carried out during five generations, were compared. In the first (GS) individuals were selected based in the estimation of markers effects and mated randomly. In the second (GS+MA) from the all possible matings, we choose the best ones based on the dominance prediction of the mating. The true genotypic value of the offspring was also calculated. We conclude that mate allocation can improve the expected genetic response on the first generation, but its advantage is not improved over subsequent cycles of selection. | |
