Question

Quizplus · Accepted Answer

Elaborate courtship behaviors are a form of behavioral isolation, as they are specific behaviors that individuals of the same species use to recognize and choose appropriate mates. The blue-footed booby's courtship behavior is a well-known example of this type of reproductive barrier. Mechanical isolation refers to physical incompatibilities that prevent mating or fertilization, temporal isolation refers to differences in breeding seasons or times, postzygotic isolation refers to barriers that arise after fertilization (such as hybrid inviability) that prevent successful reproduction, and hybrid sterility refers to the inability of hybrids to produce viable offspring.
