Document Summary
How many females he can mate with in a given breeding season. Males will compete for the opportunity to breed. Competition has lead to exaggerated male traits that are used to attract females or. In order to gain the attention of possible females. The quality of the male(s) she mates with engage in combat. This is sexual selection: natural selection for sex-specific traits related to reproduction. Sexual dimorphism: difference in male and female phenotypes improve her own fitness. A female"s preference for particular male traits should be tied to features that. Selecting for traits that will be passed down from that male to her own offspring. Several hypotheses are used to explain the evolution of female choice. Males with a specific trait have better genes than others. Good genes may be demonstrated behaviorally long call males are healthier in gray tree frogs long call offspring fed more and grew faster, size determines sexual maturity.
