Question

______ speciation occurs in geographically separated populations.

• A. Allopatric
• B. Sympatric
• C. Parapatric
• D. None of the above

Answer 1

The correct option is A Allopatric

Allopatric speciation occurs in geographically separated populations.

Allopatric speciation or geographic speciation is a speciation that occurs when biological populations of the same species become vicariant, or isolated from each other to an extent that prevents or interferes with genetic interchange.

Sympatric speciation is the process through which new species evolve from a single ancestral species while inhabiting the same geographic region.

Parapatric speciation is extremely rare. It occurs when populations are separated not by a geographical barrier, such as a body of water, but by an extreme change in habitat. While populations in these areas may interbreed, they often develop distinct characteristics and lifestyles.
