Divergence in sex steroid hormone signaling between sympatric species of Japanese threespine stickleback.

Sex steroids mediate the expression of sexually dimorphic or sex-specific traits that are important both for mate choice within species and for behavioral isolation between species. We investigated divergence in sex steroid signaling between two sympatric species of threespine stickleback (Gasterost...
