Abstract

The heterozygous advantage, which benefits only certain members of a population, can be fixed as a new species characteristic if two alleles involved are incorporated into the genome as two separate gene loci. In this way, every member of a species would come to enjoy the heterozygous advantage without ever having to produce homozygotes which may be unfit.
