Question 2 Not yet answered Marked out of 1:00 Flag question Suppose that an allele is present in pelican offspring that causes a nestling to share its food with its nestmate if it is not particularly hungry. This gene imposes a fitness cost of 0.2 on those who carry it, while conferring a benefit of 0.5 on the sibling who receives the additional food. Will this gene increase in frequency if two nestmates are always full siblings? Remember Hamilton's Rule. Select one: O a. No, because rb = c O b. No, because rb cQuestion 3 Not yet answered Marked out of 1.00 P Flag question Which of the following terms does NOT apply to the "kinship and cooperation" model? Select one: O a. coefficient of relatedness O b. reciprocal altruism O C. Hamilton's rule d. inclusive fitnessQuestion 4 Not yet answered Marked out of 1,00 Flag question Predator-prey interactions are one type of antagonistic coevolution. Which of the following traits would natural selection favor in these interactions? Select one: O a. Natural selection will favor traits in prey that increase the chance of escaping predation and traits in predators that increase their chance of capturing and killing prey, resulting in an evolutionary arms race. O b. Natural selection will only favor those traits that help predators capture their prey, resulting in an end to the evolutionary arms race. O C. Natural selection will favor traits that help the prey species and negatively impact the predator species. . d. Natural selection will only favor those traits that help prey escape predation.Question 5 Not yet answered Marked out of 1.00 P Flag question Which of the following relationships is NOT an example of coevolution? Select one: O a. A male prairie dog barking a warning call in the presence of predators. O b. Monarch butterfly larvae that feed only on milkweed plants that are not toxic to the monarch larvae but toxic to other animals; the butterflies provide pollination for the milkweed plants. O C. Ants that live in the thorns of Acacia trees; the trees provide a home for the ants while the ants protect the trees from other predators. O d. The mutualism between fungi and algae that form lichen species.Question 6 Not yet answered Marked out of 1.00 Flag question If the prisoner's dilemma game is played only once, what would we expect to see? Select one: O a. The only Nash equilibrium is defection. O b. We would expect to see cooperation. O C. It is impossible to predict based on game theory O d. We would expect to see one player testify (defect) and one player refuse to testify (cooperate).Calculate the coefficient of relatedness () between you and your first cousin. Select one: O a. r = 0.625 o b. r= 0.125 c. r= 0.50 O d. r= 0.25
