β¦ Synopsis
Mark-release-recapture experiments performed with natural populations of Drosophila at Mather, California show that flies tend to return to their area of original capture or an area ecologically similar to it. Such habitat choice explains the microgeographic genetic differentiation we observed in the population. This behavioral difference between the flies may have a genetic component or may be environmentally induced. Either way, the results help explain how high levels of genetic variation are maintained by natural selection in these species.

Inversion polymorphism has been studied in three natural populations of Droso~~iIa anana~sae. The three cosmopolitan inversions have been detected in all the three populations analysed. Some quantitative variations in the inversion frequencies seem to exist and the level of inversion heterozygosity
