6. Consider the answers to questions 4 and 5. What is the most likely explanation for this pattern? Of the four answers below, two are correct. Select the two you think are correct.

a. Under a male-biased sex ratio, short-copulation males fertilize fewer eggs during a single mating than they do under a female-biased sex ratio.

b. Under a female-biased sex ratio, short-copulation males can mate with many more females during a period of time than long-copulation males.

c. Under a male-biased sex ratio it takes a male a long time to find a new mate. Therefore, it makes more sense for a male to remain mating with his current partner than to spend a long time trying to find another female.

d. Under a female-biased sex-ratio, females are not as receptive to long-copulation males as they are to short-copulation males.
