Biology Question on Hardy-Weinberg Principle
Which one of the following factors will not affect the Hardy-Weinberg equilibrium?
A
Genetic recombination
B
Genetic drift
C
Gene migration
D
Constant gene pool
Answer
Constant gene pool
Explanation
Solution
The Hardy-Weinberg equilibrium assumes that allele frequencies in a population remain constant unless disturbed by factors such as:
- Genetic drift : Random changes in allele frequencies.
- Gene migration : The movement of alleles between populations.
- Genetic recombination : This can introduce new combinations of alleles.
- Constant gene pool : A constant gene pool (no mutation or migration) is part of the assumption of the Hardy-Weinberg equilibrium, so it will not affect the equilibrium.
Thus, the correct answer is (3).
