Which one of the following is INCORRECT about genetic drift?
Which one of the following is INCORRECT about genetic drift?
Options
- AGenetic drift is also called the Sewall Wright Effect.
- BThe effect of genetic drift is more significant in large populations.
- CGenetic drifts are directionless.
- DSometimes a few individuals become isolated from large populations and produce a small new population in a new geographical area.
Correct answer
B. The effect of genetic drift is more significant in large populations.
Step-by-step 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.
