Sexual conflict
Sexual conflict occurs when the genetic interests of males and females diverge. Recent evidence supporting the view that male and female genomes are in conflict has now revolutionized the way in which we interpret interactions between the sexes, and suggests that sexual conflict is a potent force in male–female coevolution. Here, we consider the nature of sexual conflict and what distinguishes ...
متن کاملSexual conflict
What determines male mating rate? New research is highlighting the potential importance of variation in reproductive organ size in determining the limits of male mating frequency and reproductive success. The accessory glands provide the material required to synthesise the spermatophore in which the sperm, produced by the testes, are packaged. Male mating rate is both phenotypically and genetic...
متن کاملSexual conflict in hermaphrodites.
Hermaphrodites combine the male and female sex functions into a single individual, either sequentially or simultaneously. This simple fact means that they exhibit both similarities and differences in the way in which they experience, and respond to, sexual conflict compared to separate-sexed organisms. Here, we focus on clarifying how sexual conflict concepts can be adapted to apply to all anis...
متن کاملIntralocus sexual conflict.
Intralocus sexual conflict occurs when selection on a shared trait in one sex displaces the other sex from its phenotypic optimum. It arises because many shared traits have a common genetic basis but undergo contrasting selection in the sexes. A recent surge of interest in this evolutionary tug of war has yielded evidence of such conflicts in laboratory and natural populations. Here we highligh...
متن کاملSexual Conflict in Nonhuman Primates
Locked together by their need for partners in sexual reproduction, the sexes undergo an antagonistic dance to the music of time.. . .the 'evolutionary dance' that has been used as a metaphor to describe the process of sexually antagonistic coadaptation may be better regarded not simply as a couple moving across a dance floor, but as a couple who leave a trail of destruction that they must negot...
