Which one of the following is INCORRECT about genetic drift?

Options:

Answer:
B
Solution:

Genetic drift refers to the random fluctuations in allele frequencies from one generation to the next. It is a directionless process.

It is also known as the Sewall Wright effect.

The effect of genetic drift is highly significant in small populations, not large populations, because random changes have a much larger proportional impact when the number of individuals is small.

The founder effect is a type of genetic drift where a few individuals become isolated from a larger population and establish a new population in a different geographical area.

Therefore, the statement that the effect of genetic drift is more significant in large populations is incorrect.

Answer: The effect of genetic drift is more significant in large populations.
