Abstract:
The influence of unbalanced mating systems - factorial mating (FM) and random loss of families after a full diallel crossing (RS) - on the ultimate probability of gene fixation (u(Π)) and the time required to fix or lose a gene (t(Π)) are investigated. The average u(Π) of these systems is smaller than that of random mating, and the range of u(Π) for a given initial parental genotype combination is very large (close to one for most initial genotypic combinations). The average u(Π) of different parental genotypic combinations of a given gene frequency are different. These systems accelerate the t(Π).
