2004 Rowe 26. If we could do an experiment on Katydids where we fed females a lot, but fed males only a little, which result is most likely to be CORRECT? a. Given the opportunity, males would mate infrequently. * b. Given the opportunity, females would mate frequently. c. Males would call frequently. d. Females would produce few offspring. e. Males would produce few offspring. If males are food deprived, given the opportunity, they will tend to mate infrequently (a). This is because they cannot gather the energy required to produce the nuptial gifts given at mating. These data were given in slide # 36 in Lecture 17. 28. Which case that we discussed in class was NOT an example of mate choice resulting from direct benefits? a. Female choice in Hanging Flies. b. Female choice in water striders. c. Choice of large females in Morman Crickets. d. Female choice of elaborate bowers in Bowerbirds. * e. Male choice of elaborate females in pipefish. The correct answer is "Female choice of elaborate bowers in Bowerbirds" (d). This example was discussed at slides #26-27 in Lecture 16. In this species, males transfer nothing but sperm, and there is no other association between partners. Therefore, any benefit to females of choosing must resign in male genes. Consequently, it is an example of indirect benefits. All other options in the question are examples of direct benefits. The one that seemed to confuse people was the water strider option. This was explained as an example of direct benefits at slides #41-42 of Lecture 18. 32. Which statement about phenotypes is most likely to be CORRECT?
