Mating system manipulation and the evolution of sex biased gene expression in Drosophila

Mating system manipulation and the evolution of sex biased gene expression in Drosophila

... Different gene expression optima in the two sexes underlie the evolution of sex-biased gene expression. Sex-limited gene expression may resolve intra-locus conflict, and is likely in sex- specific tissues such as testes ...
