Multiple choice

What is allopatric speciation?

  1. The process of two populations becoming geographically isolated and evolving into distinct species

  2. The process of two populations becoming genetically isolated and evolving into distinct species

  3. The process of two populations becoming reproductively isolated and evolving into distinct species

  4. The process of two populations becoming ecologically isolated and evolving into distinct species
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Allopatric speciation is the process of two populations becoming geographically isolated and evolving into distinct species, often due to vicariance.

Multiple choice

  1. Natural selection

  2. Genetic drift

  3. Gene flow

  4. Mutation
Reveal answer Fill a bubble to check yourself
