Abstract: In animal breeding after selection of the breeding animals a second step is introduced: the matching of a male and a female.This mating can occur randomly or assortatively.Primary reasons for the application of mating are exploitation of non-additive genetic effects (preference of heterozygote), anticipating on non-linearity of profit functions (profit heterosis, maintain or reach optimum level in progeny, and avoid extremes or specific classes), and the desire to influence genetic (co)variances (reduce variability, increase variance to maintain or increase possibilities for selection, restrain inbreeding, and effects on genetic correlations).This paper gives an overview on definitions and applications and details some theory on the influence of mating on genetic (co)variances.
