- You are studying a genetically modified mouse that produces electric blue fur, which is not a fur color observed in nature. You notice that females prefer males that have the blue fur when given a choice test for mates. This result supports which of the following models of sexual selection? a. Sexual selection for indirect benefits b. Sexual selection for direct benefits c. Sexual selection for arbitrary traits d. None of the abovearrow_forwardIdentify each of the following statements as being most similar to a hypothesis, a law or a theory. Explain your reasoning. A. Dogs like to chase bunnies. B. By identifying the gene responsible for triggering the predation response, breeders could develop a dog that will not chase bunnies. C. The predatory behavior of dogs towards smaller animals is due to their close genetic relationship to wolves.arrow_forwardIn Biology of Beauty, Cowley found that contemporaryfemales are attracted to males with broad foreheads and strong chins, and that this effect persisted across different cultures. How did Cowley explain this result? A. This is a trick question- this attraction is culturally relative B. Males compete for access to females by developing these features as a form of male-male competition C. There is no evidence that females really are differentially attracted to males with these features D. Attraction to males with these features is adaptive for females because males with these traits are usually sexually mature and have healthy immune systems E. Only some human cultures value these traits as attractive.arrow_forward
