Allopatric speciation is due to:

Allopatric speciation is due to: Correct Answer Geographical isolation

Concept-

  • ​Speciation is the evolutionary process by which populations evolve to become distinct species.
  • A Speciation takes place when variation occurs with geographical isolation.
  • Speciation basically takes place due to the variation of an organism's death, changes due to accident, Geographical isolation, etc.
  • There are five types of speciation: allopatric, peripatric, parapatric, and sympatric, and artificial.

Explanation-

  • Allopatric speciation, the most common form of speciation, occurs when populations of a species become geographically isolated. 
  • Allopatric speciation occurs when the biological populations of the same species get isolated from each other to such an extent that their gene flow gets restricted.

Thereby Allopatric speciation is due to geographical isolation.

Additional Information

  • Sympatric speciation occurs when all the organisms from a species are in close proximity to one another and no physical barriers can prevent them from mating with one another.
  • Parapatric speciation occurs when a species is spread over a large geographic area and individuals mate with only those who are present in the same geographic region.
  • Peripatric speciation occurs when a small group of individuals separates from a larger group and forms their own new species
