Social selection in human populations: protected polymorphism of deleterious alleles with incomplete penetrance.


Population dynamics of two alleles, A1 and A2, at a locus under social selection have been studied by considering incomplete penetrance of the three genotypes. A social selection model is constructed by assuming that the fitness of an individual is determined by his or her own phenotype as well as parental phenotypes. For both multiplicative and additive… (More)
