Which one of the following factors will not affect the Hardy-Weinberg equilibrium?
- Genetic recombination
- Genetic drift
- Gene migration
- Constant gene pool
Answer
(4) Constant gene pool
Solution
Five factors affect Hardy-Weinberg equilibrium: gene migration (gene flow), genetic drift, mutation, genetic recombination and natural selection.
A constant gene pool (allele frequencies unchanged over generations) is the condition of the equilibrium itself, so it does not disturb it.
