The Genetic Basis of Differences Between the Sexes (2007–2012)
The contrasting roles of the sexes in reproduction reflect severe conflicts within the genome that drive the evolution of sex-differences in numerous traits (sexual dimorphism). Nonetheless, we still have much to learn about how the sexes can evolve and express contrasting phenotypes whilst sharing a genome. Exciting advances in theory and evidence point to novel research directions that promise to illuminate key aspects of gene function and heredity. Using the powerful techniques of molecular and quantitative genetics, artificial evolution and manipulations of environment, in conjunction with natural variation in two Australian insects, we will build on these advances to illuminate the genetic basis of differences between the sexes.
