| Abstract: | Summary Functionally significant biochemical properties of the naturally occurring electrophoretic variants at the Adh locus (ADHfast and ADHSlow) are correlated with the adult flies' ability to utilize and survive in an ethanol environment. The results are consistent with the idea that an environmentally dependent form of balancing selection is responsible, at least in part, for the maintenance of the polymorphism at this locus.Acknowledgment.
