The correct answer is: A.Allopatric speciation involves geographic separation, while sympatric speciation does not

Explanation:

The primary difference between allopatric and sympatric speciation lies in the geographic separation of populations.

1.Allopatric speciation occurs when a population is geographically isolated by a physical barrier (like a mountain, river, or ocean). This isolation prevents gene flow between the separated populations, and over time, genetic differences accumulate, leading to the formation of new species.

2.Sympatric speciation occurs when new species arise within the same geographic area, without any physical barrier. In this case, reproductiv...
