In species where females provide all of the care for their offspring, males compete for mates. b. In species where males compete for mates, the males try to dazzle their mates, whereas in species where females compete for mates, the females fight aggressively for access to mates. c. In monogamous species with biparental care, courtship is mutual (each sex courts the other). d. In some species (such as stickleback fish) where males provide all of the parental care, males still compete intensely for mates. e. Mating competition never occurs in females.
