Intralocus sexual conflict occurs due to the expression of sexually antagonistic alleles: those that increase fitness when expressed in one sex but decrease fitness when expressed in the other sex. This genetic conflict is expected whenever the sexes are selected toward differing phenotypic optima for a trait that has a positive genetic correlation between the sexes. Here we synthesize recent developments in the areas of genomics, microarray analysis, and developmental and molecular genetics to establish feasible mechanisms by which the intersexual genetic correlation can be reduced, as well as the time course over which conflict resolution is expected to evolve.
