A general theory of the distribution of gene frequencies. II. Non-overlapping generations.

The distribution of gene frequency a t a single locus in a population of diploid individuals, w ith two sexes, subject to m utation , non-random m ating and phenotypic selection, is obtained in the case where the generations are overlapping so th a t individuals die one by one. This d istribution is of the same form as th a t obtained by heuristic m ethods by S. W right in a random ly m ating population b u t the coefficients are a ltered bo th by the non-random ness of the m ating and the overlapping of the generations.
