Two interesting cases of continued mating in monogenic and digenic systems

Abstract

Mating with a heterozygote, continued across generations, has been investigated anew. An interesting single-gene system under this continued mating is presented and shown to extend, in general, to two genes. Based on the results, a possible modified biparental mating system of high practical significance is highlighted. Likewise, under continued selfing, the mean value of a quantitative trait has been derived, for the first time, in terms of recombination fraction and additive-additive interaction in a two-gene system.
