Genetic divergence in M. Vetukhiv's experimental populations of <i>Drosophila pseudoobscura</i> 2. Longevity

Abstract

Six experimental populations of Drosophila pseudoobscura were maintained in three different environments for almost four and a half years. All the populations have originally descended from the same founders. The populations were examined for evidences of genetic divergence. The longevity of the flies from four of these populations, and their F 1 and F 2 hybrids, was studied at 16°C. and at 27°C. The results indicate that the gene pools of some of the populations have diverged from each other.
