Question

gentoo penguins present a potential mate with a pebble. emperor penguins have a specific call and movement that they make to attract a mate. which type of isolation do these penguins demonstrate? geographical isolation behavioral isolation anatomical isolation temporal isolation

Explanation:

Behavioral isolation occurs when different species have distinct courtship behaviors (like the Gentoo's pebble presentation and Emperor's specific call/movement) that prevent interbreeding. Geographical isolation is about physical barriers, anatomical about physical incompatibility, and temporal about different breeding times—none match here.

Answer:

B. behavioral isolation
