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
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?

Other bird species are seasonally monogamous: they choose a new mate every year. Some bird species have what is called helpers-at-the-nest; these helpers are older offspring who stick around and assist their parents in taking care of babies born the next year. Kin selection would predict that you would find more instances of helpers-at-the-nest in the species that mate monogamously for life than in the seasonally monogamous species. Why? Be sure to address why they might still help in seasonally monogamous pairs.arrow_forward why do females have a greater disadvantage compared to males concerning sexual reproduction?

- Intrasexual selection favors traits that enhance direct competition among individuals of the same sex. are attractive to the opposite sex. increase survival. are easily adapted to change.arrow_forwardIn one year, there were 18 males and 34 females. Over the following year, each female gave birth, of which 28 survived. Nine elephants died due to predators. A construction project cleared 50 acres of nearby forested land, causing 5 males and 19 females to immigrate into the experimental area. Competition for females increased, resulting in the emigration of 10 males to a new territory in search of mates.arrow_forwardMatch 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. The impressive feathers of a male peacock are the result of this type of sexual selection All Answer Choices A.

- Assume that a scorpion presents a meal to a partner to entice them to mate. This would be an example of which of the following? Delayed Benefits Indirect Benefits Intrasexual selection Direct benefitsarrow_forwardIntrasexual 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.arrow_forwardWhat difference in size of feral cat, domestic cat that has both indoor and outdoor lifestyle, street cat?
