A BIOGEOGRAPHIC GENETIC APPROACH FOR TESTING THE ROLE OF REINFORCEMENT: THE CASE OF DROSOPHILA PSEUDOOBSCURA AND D. PERSIMILIS
Abstract
The role of reinforcement in speciation can be explained by two distinct models. In model I, two diverged populations hybridize and produce fertile hybrids that successfully backcross (hybridization with gene flow). In model II, two populations hybridize but succeeding backcrosses are unproductive (hybridization without gene flow). Using Drosophila persimilis and D. pseudoobscura, we have tested model I by comparing the extent of heterospecific …
