Answer 2

Correct option is

The speciation can happen the genetic difference between two populations.

Explanation:

Genes flow is defined as population genetics when the gene flow allows transfer of genetic material from one population to another.The other name is gene migration which has similar meaning.

1. When gene flow is blocked or reduced by physical barriers, it results to Allopatric speciation or a geographical isolation.
2. It does not allow populations of the same species to exchange genetic material.
