Abstract

A STABLE selectively balanced polymorphism dependent on a pair of autosomal genes (or chromosomal arrangements) is known to exist when the heterozygote is at a selective advantage with respect to both homozygotes. It has sometimes been assumed1 that the same conditions apply also to a selectively balanced polymorphism at a locus in the X-chromosome and that the existence of heterosis may consequently be inferred when heterozygotes are found to be more frequent than homozygotes in the homogametic sex. However, these assumptions seem to be unwarranted.
