Mapping Courtship Song Genes Using Next-Generation Sequencing
Under the Biological Species Concept, species are defined by the presence of interspecific reproductive isolation, and under this model, both pre-zygotic and post-zygotic reproductive barriers are important in preventing gene flow between populations to drive speciation. My project focuses on pre-zygotic reproductive isolation in the form of courtship songs. In Drosophila athabasca, females from one population are less receptive to the courtship song of males from other populations. I plan to hybridize recently diverged, behaviorally isolated populations of D. athabasca, and use next-generation sequencing techniques to map regions in the genome that are important to courtship song and ultimately speciation.
