A geographic barrier that only partially isolates two populations, so that gene flow is reduced but not eliminated, may lead to

A) allopatric speciation.
B) sympatric speciation.
C) parapatric speciation.
D) none of the above

Parapatric Speciation

Parapatric speciation is the evolution of new species within a spatially extended population that still has some gene flow.

Allopatric Speciation

The evolution of new species after populations have been separated geographically, preventing gene flow between them.

Sympatric Speciation

The evolution of new species within a contiguous population that still has extensive gene flow.

  • Understand the mechanisms that lead to different forms of speciation.

Final Answer :
C
Explanation :
Parapatric speciation occurs when populations are separated by a geographic barrier that does not completely isolate them, allowing for reduced but not eliminated gene flow.
