Explain how mutations, natural selection and genetic drift affect Hardy Weinberg equilibrium.

Explanation

Hardy-Weinberg equilibrium in a population is stable from generation to generation in the absence of mutation, genetic drift, recombination and narural selection .
Mutation is an important fator to alter Hardy-Weinberg equilibrum because new alleles are generated by mutation in a population due to duplication or deletion of chromosomes.
Genetic drift can also alter the equilibrium because of gene flow from the population due to movement of individuals from the population .
Natural selection does not produce any genetic variation, Such variations if occur in a population, is favours some genetic changes while rejecting . This may alter the Hardy- Weinberg equilibrium.
