The study of genic variation by electrophoretic and heat denaturation techniques at the octanol dehydrogenase locus in members of the Drosophila virilis group.

Abstract

Heat denaturation studies of three different electrophoretic allozymes of octanol dehydrogenase were performed from 10 species of the Drosophila virilis group. A total of 18 alleles were discovered, and in 3 species in which electrophoretic studies indicated that the locus was monomorphic, heat denaturation showed that the locus was polymorphic. We show that electrophoretic studies underestimate the number of alleles at this locus by a factor of 2.6 in these species. The results are discussed in the light of the continuing controversy over selection and neutral theories of genetic variation.
