The correct answer is option B, that is, Genetic drift greatly affects small populations, but large populations can recover.  

Genetic drift in combination with mutation, natural selection, and migration is one of the most fundamental mechanisms of evolution. Genetic drift refers to a change in the relative frequency of distinct genotypes in a small populace, owing to the chance vanishing of specific genes as individuals do not reproduce or die.

Pls help everyone is using me for points if you use me for points I'll report (;​
g100num [7]

Answer:

OH LOL I DID THIS IN 7TH GRADE

Explanation:

so if i remember when the trees where white the pepper moths that where white survived more often that the black ones, then when the industrial war came the trees where covered in ash, so the white moths survived

MY SENTENCE

It shows how a change in an environment can effect a species natural selection, for example the white moths survived more than the black moths so the reproduced while the black moths where eaten by predator's, then when the environment changed and favored the black moths they survived and reproduced while the white moth got picked off by predators.

Hope this helped mate :>
