Question

Imagine two populations of penguins live in the same ecosystem. One population begins to exchange stones as a mating ritual while the other population begins to dance by shifting from one foot to the other. Individuals from each population will only mate with individuals that display the appropriate mating ritual. Which type of reproductive isolation mechanism does this scenario describe?(1 point)

Answer 1

Behavioral Isolation

Because the two penguin groups use different mating displays (stone-exchange vs. foot-shifting), they only mate with individuals showing their own ritual, a form of behavioral (prezygotic) reproductive isolation.
