Sexually Antagonistic Selection, Sexual Dimorphism, and the Resolution of Intralocus Sexual Conflict
Haven't read much on this particular topic, but given direction that my thesis is going I gotta start brushing up on the sexual selection literature. Anyway, this unusual review discusses the importance of sexual selection from an intra-locus perspective the essential idea being that in sexually dimorphic species single locus traits may be under different selective regimes depending upon the sex in which they are expressed (= sexually antagonistic selection). The authors find, with some caveats, that sexually antagonistic selection may be present in as many as 17% of species that exhibit sexual dimorphism.
