"Insights in Sex Chromosome Evolution from Genetic Mapping" is presented by Paris Veltsos, Ph.D., a postdoctoral fellow in the Department of Biology at Indiana University.
"I am interested in the evolutionary forces that shape sex chromosomes, such as sexual selection, and their implications to reproductive isolation. I have worked on a variety of organisms (grasshoppers, Drosophila, frogs, plants) and used theoretical models, field and lab populations (including experimental evolution) to investigate these questions. My main project at Indiana University is testing the prediction that sexually antagonistic traits (those that are beneficial for one sex but deleterious for the other) are enriched on the pseudoautosomal region of the sex chromosomes. We are performing a QTL study on >30 traits, some of which are sexually antagonistic, using a cross between plant populations (S. latifolia) that are adapted to different environments. The associated genetic map also allows us to directly identify locations of the genome that are potentially sexually antagonistic by being associated with sex more often than chance."
