Question 1 (2 points) Males of certain bedbug species transmit sperm by punching their genitalia through the female's body wall and ejaculating. Which of the following is likely to be most directly responsible for such an extreme male mating strategy? sperm competition Question 2 (2 points) Think about how we organized the mechanisms of sexual selection (mate competition vs. mate choice; resource- based choice vs. non-resource-based choice, etc.). Based on this organization, choose the pair of examples from the list below that are most closely matched in terms of mechanisms of sexual selection. Hyla versicolor tree frog females prefer to mate with males with long calls. Female amphibious blennies, a type of fish, choose males that have dorsal fins with a great deal of red coloration. Question 3 (1 point) Sexual dimorphism refers only to differences in size between the sexes. False Question 4 (3 points) 1.5 out of 3 From the list below, select those that are examples of mate choice involving indirect benefits. Swordtail characin mating with male that has an especially large paddle. Female pipefish mating preferentially with a male that has the showiest 'ornaments'. Preference in house finches for genetically complementary males The larger male red deer winning a physical contest with its opponent. Female Anthidium bee mating with male that is defending the richest patches of flowers.

Female tungara frog responding to male of same species but not male of another species. Question 5 (2 points) Think about how we organized the mechanisms of sexual selection (mate competition vs. mate choice; resource- based choice vs. non-resource-based choice, etc.). Based on this organization, choose the pair of examples from the list below that are most closely matched in terms of mechanisms of sexual selection. Male red deer engage in physical contests to determine who mates with a female. Male mouse lemurs engage in scramble competition for female mates. Question 6 (2 points) 0 out of 2 Think about how we organized the mechanisms of sexual selection (mate competition vs. mate choice; resource- based choice vs. non-resource-based choice, etc.). Based on this organization, choose the pair of examples from the list below that are most closely matched in terms of mechanisms of sexual selection. Male bird has genes for parasite resistance that will be passed on to his offspring. Male butterfly transfers sodium to female during mating, which female uses. Male roadrunner presents female with lizard 'snack' during courtship. Question 7 (2 points) 1 out of 2 What selection pressures taken together are thought to have driven the evolution of anisogamy? Check all that apply. Gametes able to resist sexually-transmitted disease (STD). Gametes, once fertilized, better at developing to adulthood. Gametes effective at fertilizing other gametes. Gametes both fast-moving and full of nutrients for the future embryo. Question 8 (2 points)

Some models of mate choice involve positive feedback that lead to the evolution of exaggerated male traits. Check the two models in the list below in which positive feedback occurs. Fisher's Runaway Selection Model Bright Birds and Parasites Model
