Abstract

The rapid fixation of a rare allelic form of alpha-glycerol phosphate dehydrogenase is related to a loss of competitive ability in nature of factory-reared screwworm flies. The increase in frequency results from selection for survival under conditions of domestication and rapid development at high constant temperatures in the factory.
