The Response of Enzyme Polymorphisms to Developmental Rate Selection in DROSOPHILA MELANOGASTER.
Two strains of Drosophila melanogaster derived from different geographical localities were subjected to selection for fast and slow developmental rate. Four enzyme polymorphisms were monitored for their response to such selection. Significant changes in allele frequencies were effected for the alphaGpdh and 6Pgd polymorphisms under fast developmental rate selection. The strain from Rhode Island exhibited a correlated change in body weight during developmental rate selection, whereas the Georgia strain did not.
