Reproductive isolation in natural populations of Drosophila melanogaster from Brazzaville (Congo).
The aim of this work is to analyze the homogamy previously detected between two natural populations of Drosophila melanogaster from Brazzaville. It is shown that mating isolation was still maintained under laboratory conditions 10 years after the populations samples were trapped. Isolation seemed to be due mainly to premating isolation and we checked for any suggestion of post-mating mortality of hybrids. Pre-mating isolation was not symmetrical, and significant chi2 values were found in 3/4 ...Expand abstract
