Final answer:
Intersexual selection and intrasexual selection are two types of selection that occur during the process of finding a suitable mate in sexually reproducing animals. Intersexual selection involves individuals of one sex choosing mates of the other sex based on various cues, while intrasexual selection involves competition for mates between individuals of the same sex.
Step-by-step explanation:
Intersexual selection and intrasexual selection are two types of selection that occur during the process of finding a suitable mate in sexually reproducing animals.
Intersexual selection involves individuals of one sex choosing mates of the other sex based on various visual, aural, tactile, and chemical cues. An example of intersexual selection is when female peacocks choose to mate with the male with the brightest plumage.
Intrasexual selection, on the other hand, involves competition for mates between individuals of the same sex. This competition often includes mating displays and aggressive rituals to determine which individual is able to mate. The winner is typically the healthiest, strongest, and most dominant individual.
