Genetic Surprise Confirms Neglected 70-Year-Old Evolutionary Theory

Most of Orr's research focuses on the genetics of speciation and the genetics of adaptation. In particular, he is interested in the genetic basis of hybrid sterility and inviability. He studies these problems through genetic analysis of reproductive isolation between species of Drosophila. In his adaptation work, Orr is interested in theoretical rules or patterns that might characterize the population genetics of adaptation.
