 **Abstract:** Female mating preference for conspecific males involves the evolution of new traits that allow individuals to recognize conspecifics *and* discriminate against heterospecifics. My group is leveraging the power of *Drosophila* genetics to identify the genetic, ethological, and neurobiological basis of female mating choice in a classic case of incipient speciation: the two races of *D. melanogaster*—called Cosmopolitan (*M*) and Zimbabwe (*Z*). These two races show strong behavioral isolation in the form of *Z* female mate choice; *Z* females strongly prefer to mate with males from their own race. Such a complex behavioral trait integrates signals on multiple sensory channels and is likely caused by changes in multiple genes; the precise genetic basis for this preference has remained unknown. Using multiple mapping approaches (i.e., complementation mapping, introgressions, admixture mapping), we discovered *Z* alleles involved in female mating choice. These results indicate that we can map the genetic basis of female preference despite it being polygenic, and will inevitably lead to a better understanding of the molecular basis for behavioral reproductive isolation.

 **Host:** Hopkins Lab
