Which of the following describes allopatric speciation?
A) Gene flow between subpopulations minimizes differences in their gene pools.
B) A single population suddenly divides into two reproductively isolated groups without being geographically isolated.
C) A geographic separation occurs between subpopulations leading to reproductive isolation.
D) Wide phenotypic differences that appear between subpopulations due to variation in their environments.
E) Subpopulations that are geographically isolated but still able to interbreed.
Allopatric Speciation
Model that proposes that new species arise due to an interruption of gene flow between populations that are separated geographically.
Geographic Separation
The physical separation of populations by geographic barriers that lead to the formation of distinct species over time.
- Comprehend the role of reproductive isolation in species formation.
- Comprehend the procedure and result of species formation.

Final Answer :
C
Explanation :
Allopatric speciation occurs when a geographic separation occurs between subpopulations leading to reproductive isolation. This isolation can result in the accumulation of genetic differences between the two groups, eventually leading to the development of distinct species.
