Which provides the most general and correct description of the idea of a reproductive barrier?

Question

Quizplus · Accepted Answer

A reproductive barrier is a biological difference or mechanism that prevents two species from interbreeding and producing viable offspring. This can include differences in DNA sequence, chromosome number, mating behavior, or reproductive anatomy. Option A describes a geographic barrier, which can contribute to reproductive isolation, but is not a reproductive barrier in and of itself. Option B also represents a form of reproductive isolation, but is too narrow of a definition to encompass all forms of reproductive barriers. Option D is the most broad, but does not specify that the barrier must be biological in nature. Option C is the most general and correct description of a reproductive barrier, as it includes all possible mechanisms of reproductive isolation.
