375:, red facial coloration is attractive to females to the point of influencing the reproductive success of high-ranking males. To be deemed a sexually selected trait said trait must be heritable and confer a reproductive advantage. In this example, facial redness is heritable, but only increases a male's reproductive success if he is also high-ranking, and rank is not determined by facial redness (dominance in rhesus macaques is not competition-based but rather queue-based). While this trait is believed to be the result of intersexual selection, such examples demonstrate the complex nature of determining evolutionary explanations for sexually dimorphic characteristics.

gestation, lactation, and infant care are all highly energetically costly processes for females, so these energy and time constraints would lead them to choose—when possible—mates with higher quality genes leading to higher quality offspring with a better chance of survival and reproductive success. Importantly, what is deemed “high quality” by the female in this instance need not confer a survival advantage to the male, but must be perceived by females as a sign of attractiveness if not health. A common example of this is sexually dimorphic coloration.
305:), one of the African guenon species, have shown that call rates in adult females (24 call.hr-1) are more than seven times higher than in adult males (2.5call.hr-1). A usage of different call types also differs between sexes, in that females mostly utter contact(-food) calls, whereas males produce a great number of threat calls. Such difference in vocal usage is associated with social roles, with females being involved in more social tasks within the group and males being responsible for territory defense.
336:. Male baboons are known to violently fight and threaten each other over females and show high levels of sexual dimorphism in body and canine size, both of which are assumed to aid in combat. The “winners” of such interactions mate with the desired female and produce offspring, passing their traits to the next generation, while unsuccessful males are excluded from mating. As a result, traits beneficial to fighting are selected for in the population over time.

Male mandrills also possess a yellow beard, nuchal crest of hair, and pronounced boney paranasal ridges, all of which are absent or vestigial in females. Studies have shown that male color in mandrills serves as a badge of social status in the species.
