Interlocus sexual conflict
Interlocus sexual conflict is a type of sexual conflict that occurs through the interaction of a set of antagonistic alleles at two or more different loci in males and females, resulting in the deviation of either or both sexes from the fitness optima for the traits.
Interlocus sexual conflict involves a co-evolutionary arms race between the two sexes in which either sex evolves a set of antagonistic adaptations that are detrimental to the fitness of the other sex. Interlocus sexual conflict can occur over aspects of male–female interactions such as mating frequency, fertilization, relative parental effort, female remating behavior, and female reproductive rate. The evolutionary pathways resulting from interlocus sexual conflict form part of interlocus contest evolution.
== Interlocus versus intralocus sexual conflict ==
The genetic basis of the distinction between interlocus sexual conflict and intralocus sexual conflict is the location of the interacting antagonistic alleles. Conflict in which the antagonistic alleles are located at the same locus is termed intralocus sexual conflict, and conflict in which the antagonistic alleles are located at different loci in both sexes is termed interlocus sexual conflict. Intralocus sexual conflict occurs when males and females undergo different selective pressures at the same locus, resulting in either sex limiting the evolution of the other sex. In contrast, interlocus sexual conflict occurs when males and females undergo different selective pressures at different loci, potentially leading to agonistic coevolution.
