Question

6 multiple choice 1 point which of the following best explains allopatric speciation? species evolve in the same environment with no isolation a mutation causes instant reproductive isolation hybrid species arise within one population populations become geographically separated and evolve independently

Explanation:

Allopatric speciation occurs when populations of a species become geographically separated. Over time, these separated populations evolve independently due to different environmental pressures, genetic drift, and natural selection. Eventually, they may become so different that they can no longer interbreed, leading to the formation of new species.

• The first option is incorrect because allopatric speciation requires geographical isolation.
• The second option describes sympatric speciation (instant reproductive isolation due to mutation without geographical separation) rather than allopatric.
• The third option is also incorrect as allopatric speciation involves separated populations, not a single population giving rise to hybrids in the context of allopatric speciation.

Answer:

Populations become geographically separated and evolve independently
