Genetic drift is stronger than natural selection in small population because:

a. There are more mutations, some of which can be beneficial

b. Genetic drift can erode allelic variation in small populations, even eliminating beneficial mutations

c. Drift is non-random

d. it leads to higher fitness

Solution

The answer is: b. Genetic drift can erode allelic variation in small populations, even eliminating beneficial mutations.

Genetic drift is stronger than natural selection in small population because genetic drift can erode allelic variation in small populations, even eliminating beneficial mutations.

There is lesser competition in small population, while in large population only fit ones survive as they outcompete the weak ones.
