Evolution of Sexual Dimorphism
Most phenotypic and functional traits are encoded by the autosomal genome, which is shared between the sexes. This shared genome should theoretically constrain the evolution of sexual dimorphism, yet there is a great diversity of sex-specific phenotypes in nature. We study the pattern and process of how this occurs. We have characterized 1) phenotypic, physiological, and life history differences between the sexes (Cox, Peaden & Cox, 2015; Reedy et al. in press) and 2) how sex-specific development is regulated (Cox, Hanninen, Reedy et al., 2015).
