Glucose-6-Phosphate Dehydrogenase in Drosophila : X-Linked Electrophoretic Variants

Abstract
Three electrophoretic patterns of glucose-6-phosphate dehydrogenase have been found in wild-type strains of Drosophila melanogaster. Genetical control of the variants in enzyme mobility (fast or slow) is X-linked; strains possessing both bands (fast and slow) appear to be heterogeneous, having individuals of three types (fast, slow, and double).
