In some jacana species, males take care of the eggs and young, and females compete among themselves for territories that contain one to several males. Female jacanas are significantly larger than males. Which of these statements would you predict to be true of this bird species?

a. Male jacana fitness is primarily limited by ability to take care of eggs and raise young.

b. Female jacana fitness is limited by the number of males in her territory with which a female mates.

c. Variation in reproductive success should be greater in male jacanas than in females.

d. Variation in reproductive success should be greater in female jacanas than in males.

e. Males and females have equal variation in reproductive success.
