Question
10 male parrots wish to mate with a female. The female chooses to mate with the male that has the brightest tail feathers.
Male giraffes perform mating dances. The ones that perform the dance better are chosen by the female as a mate.

Deep-voiced men have more children in a traditional hunter- gatherer culture, the Hazda of Tanzania. Taller men are more likely to be chosen in speed-dating competitions than their shorter rivals (Belot and Fancesconi 2006) and are more likely to be chosen as sperm donors by women in California (Egan 2006). Images of men with slightly bloodshot eyes are judged less attractive than photographs of the same men in which the whites of the eyes are clear (Provine et al. 2011).

Sex-specific infanticide occurs more often at nests that can be flooded during the rainy season. Sons spend longer in the nest than daughters. Link this factor to why it might be adaptive for a parent parrot to kill a son in a vulnerable nest occupied by offspring of both sexes. Don't write from any online source..arrow_forward
- Regarding mating behavior, choose the false statement from the list: Some aspects of courtship behavior may have evolved from agonistic interactions. Courtship interactions ensure that the participating individuals are nonthreatening and of the proper species, sex, and physiological condition for mating. The mating relationship in most mammals is monogamous, to ensure the reproductive success of the pair. Polygamous relationships most often involve a single male and many females, but in some species this is reversed. Salmon swimming against the stream to lay eggs is an example of taxis. tropism. kinesis. cognitive mapping spatial learning Female Apanteles wasps lay their eggs in caterpillars of the genus Pieris. The site of the caterpillar initiates the egg laying behavior.
