Summary
Experimental populations of Drosophila willistoni adapted to low, median and high pH substrate (pH 2, pH 5 and pH 10) were tested by the multiple choice technique, and a significant sexual preference was observed for homogamic insemination, which was greater among populations derived from the centre of the species distribution than the ones collected near the margin of its distribution range. It was also observed that some of the F1 and F2 hybrids, between flies adapted to different foods, were reproductively inferior on the parental substrate.
The greater divergence of the central populations may be due to their significantly greater chromosomal and genie polymorphism than the margins, populations.
