Here, I used deficiency mapping to locate regions that influence the rejection of D. melanogaster males by D. simulans females. First, I tested two genes that have been previously shown to affect female within-species mate choice: neither of these genes was found to contribute to between-species female preference. Next, 1identified five small significant regions that contain candidate genes contributing to behavioral isolation, which were all located in areas of low interspecific recombination.
