Sexual selection

Mode of natural selection involving the choosing of and competition for mates

Sexual selection is a mechanism of evolution in which members of one sex choose mates of the other sex (intersexual selection) to mate with, and compete with members of the same sex for access to members of the opposite sex (intrasexual selection). These two forms of selection mean that some individuals have greater reproductive success than others within a population, for example because they are more attractive or prefer more attractive partners to produce offspring. Successful males benefit from frequent mating and monopolizing access to one or more fertile females.
