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.

Sexual dimorphism (SD) is a pattern that is seen throughout the animal kingdom and differences between the sexes in coloration are common in many organisms. Following some statement are given
A) There are many mechanisms that drive the evolution of SD, the most accepted mechanism being sexual selection
