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.
