Question

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 1

The Correct Option is D

The Hardy-Weinberg equilibrium assumes no change in allele frequencies in a population, meaning no evolution occurs. The factors that can affect this equilibrium include:

Genetic drift, which causes random changes in allele frequencies, especially in small populations.

Gene migration or gene flow, which introduces new alleles into a population.

Genetic recombination, which creates new allele combinations but does not affect allele frequencies directly.

A constant gene pool is the assumption that the genetic makeup remains stable, and therefore does not affect the equilibrium.

Thus, the correct answer is (4) Constant gene pool.
