A biochemical comparison was made between ~-glycerophosphate dehydrogenase allozymes from Drosophila melanogaster. Enzymes extracted from the three major genotypes were indistinguishable in terms of their pH optima and thermal stabilities. Distinctive differences were observed for three parameters;
