Which is not a post-zygotic barrier? * Two species of ladybugs live in the same habitat. Although they mate at the same time of year, their genitals are physically incompatible. Two species of fish inhabit the same stream. They are capable of mating and producing healthy offspring. The offspring, however, are infertile. Two species of opossums inhabit the same forest. Although they are capable of mating, no offspring ever survive development. Two species of mice coexist in a forest habitat. They are capable of mating and producing offspring.

- Match the scenario to the type of sexual selection: 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. Male kangaroos fight each other, the winner claims the female to mate with. Male red-winged blackbird sing and display their feathers to establish their territories. All of the females in that territory will exclusively mate with that male.

This would be an example of which of the following? Delayed Benefits Indirect Benefits Intrasexual selection Direct benefits
- Intrasexual selection involves competition among one sex (typically males) for mating access to the other sex. Intersexual selection involves mate choice in which individuals from one sex (typically females) choose their mates from among individuals of the other sex. Imagine a group of males that is engaged in agonistic behavior, from which Male A emerges triumphant. Now imagine a female that is assessing all of the males that were involved in the fights, and chooses Male A. Explain why this situation shows how intrasexual and intersexual selection pressures are likely both at play in the trait selection.Name some traits for which you think humans exhibit nonrandom mating. Is mating for these traits likely to be positive or negative assortative mating? Name some traits for which you think people mate randomly. How could you test whether mating for these traits is random?Which of the following statements is NOT the reason why females are choosy? By being choosy, she can acquire advantageous genotypes for her offspring from her mates. By being choosy, she can acquire resource for her offspring from her mates. By being choosy, she can ensure that her male offspring can attract more females as well. Her seeming choosiness is a by-product of her stereotypical behaviors exploited by the males for mating gains. All listed above are reasons why she is choosy
