The correct option is (B) Genetic drift
Genetic drift is affected by population size.
How Hardy-Weinberg condition is affected by population size?
- One of the most important concepts in population genetics, the study of the genetic variety and composition of populations, is the Hardy-Weinberg equilibrium theory.
- For Hardy-Weinberg equilibrium to exist, there must be an infinitely large population. This state is essential to offset the effects of genetic drift.
- Genetic drift is the change in allele frequencies in a population that does not result from natural selection.
