The complex genetic architecture of male mate choice evolution between Drosophila species.

ABSTRACT: Mate choice behaviors are among the most important reproductive isolating barriers in many animals. Little is known about the genetic basis of reproductively isolating behaviors, but examples to date provide evidence that they can have a simple genetic basis. However, it is unclear if these results indicate that individual genes with large effects are common, or are instead due to ascertainment biases. Here, we present the results of a QTL mapping study for the most important behavioral isolating barrier between Drosophila simulans and D. sechellia: male mate choice. Our QTL results initially suggested that differences in male mate choice may be due to a couple loci with large effects. However, as we divided the largest-effect QTL using stable introgression strains, we found evidence of mu
