This paper looks at how the effects of intrasexual selection on the evolution of male behavior include a general promotion of superior genes, because the dominant males frequently are able through their various acquired adaptations to pass on the traits that made them dominant to their own offspring, leading to a measure of improvement in the next generation and a relative reduction in the overall number of males of the species that are weaker or exhibit other disadvantages. In conclusion, sexual selection occurs because of the varying reproductive success of genetically different males, commonly due to competition between males, or to different degrees of attractiveness to females. 4 pgs. 6 f/c. 7b.
