Dr. Hedrick's research focuses on the conservation genetics of endangered species and the genetic bases of evolutionary processes. Recent projects in his laboratory have examined the effects of inbreeding and outbreeding on fitness-related characters in Sonoran topminnows, Mexican and red wolves, and bighorn sheep. Current projects in the laboratory examine patterns of variation and factors affecting variability at major histocompatibility complex (MHC) and microsatellite loci. The MHC, whose genes are involved in immune response, are the most polymorphic loci known in many vertebrates. MHC and microsatellite variation have been examined in the Gila topminnows, desert bighorn sheep, Arabian oryx, and winter-run chinook salmon. He is also interested in theoretical research on the maintenance of genetic variation and inbreeding depression.
