چکیده

This paper presents a study of intertemporal propagation of distributional properties of phenotypes in general polygenic multi-gender inheritance models with sexand time-dependent heritability. It further analyzes the implications of these models under thick-tailedness of traits’ initial distributions. Our results suggest the optimality of a flexible one-sex/two-sex mating system. The switching between the asexual and binary inheritance mechanisms allows the population to achieve effectively a fast decline of negative traits or a quick spread of positive traits, regardless of the distributional properties of the phenotypes in the initial period.
