Two squirrel populations are said to have very little gene flow. What will most likely

happen to these populations?

a

The populations will evolve separately from each other.

b

The populations will evolve at the same rate.

c

Both populations will develop the same ratio of alleles.

d

There will be an increase in diversity within both populations.

The correct answer is option a. "The populations will evolve separately from each other".

Explanation:

Two squirrel populations that have very little gene flow will not share their genetic adaptations to survive the changing environmental conditions that they can face. Therefore, it is very likely that the two populations will evolve separately from each other. This contrasts with species that evolve collectively since they share their genetic adaptions due to a high gene flow among them.
