Replicate lines from two wild-caught populations of D. melanogaster were selected for fast, intermediate or slow development times. After 36 generations of selection, the average time to the first emergence of adults was about half a day less in lines selected for fast development than it was in the other lines. Polymorphisms for Adh and six chromosome inversions were monitored during the course of selection. Average Adh F allele frequencies become higher over the 36 generations in lines selected for fast development than in other lines. Collating this result with earlier reports, an association with development time has now been found for three enzyme polymorphisms in laboratory D. melanogaster populations selected for rapid development. Allele frequencies at all three loci show latitudinal clines in natural populations, as does development time, and for each of the three polymorphisms the allele associated with rapid development in the laboratory selection lines is also associated with rapid development in the latitudinal clines. This suggests that development time selection may contribute to the latitudinal clines for the enzyme polmorphisms. The frequencies of four inversions showing latitudinal clines generally decreased during the experiment, while two inversions not showing latitudinal clines generally persisted or increased in frequency. Only one inversion, In(3R)Mo, showed clear differences in response among different development time regimes and this inversion does not show a latitudinal cline. There was thus no evidence that geographic patterns in inversion frequencies are the result of development time selection
