Abstract A comparison of polymorphism at homologous loci between the sibling species D. melanogaster and D. simulans. — Change in frequency of homologous mutant genes sepia and vermilion in the sibling species D. melanogaster and D. simulans in competition against their wild-type alleles was followed in population cages. For each locus, allelic frequencies reach the same equilibrium level in the two species: about 0.32 for sepia and 0.27 for vermilion. These results strongly support the conclusion that selection at the sepia and vermilion loci themselves is responsible for the maintenance and the level of polymorphism at these loci, since the same type of evolution can be observed in both species without the genetic differences between these sibling species appearing to interfere.
