Which of the following statements is most accurate?
A)Biological reproductive barriers always occur after physical separation of populations.
B)Biological reproductive barriers occur as a direct result of geographic isolation of populations.
C)Geographic separation may result in biological barriers over time if populations of a species in the newly isolated regions undergo selective pressures that promote biological isolation and prevent successful reproduction if the species were to again come into contact later.
D)Biological reproductive barriers may prevent successful interbreeding even when geographic isolation has occurred,and two populations do not come into contact with each other.

Question

Quizplus · Accepted Answer

While geographic isolation can be a contributing factor to the formation of biological reproductive barriers, it is not always the direct cause. Over time, selective pressures can lead to the development of biological isolation mechanisms, even without physical separation of populations. Additionally, even if populations are physically separated, biological barriers may still prevent successful interbreeding if the populations were to come into contact again in the future. Therefore, option C is the most accurate statement.
