Abstract
Gene frequency change for the white allele in Drosophila melanogaster differed for populations kept in constant dark and constant light. The changes were explained satisfactorily by a computer program that allowed differential mating ability in males and differential fecundity in females. Although the changes in gene frequency are predictable, the system does not appear to be a good one to evaluate balancing selection in a variable environment, since the white allele becomes lost in both constant light and constant dark.
