Question

Which of the following is not a condition required to maintain constant allele frequencies of a gene in a population (Hardy-Weinberg Equilibrium)?

• A. Mating is random
• B. No natural selection is occurring
• C. No mutations occur
• D. The population is small

Answer 1

Answer: (D)

The population is small

Hardy Weinberg law or equilibrium does not apply for small populations. For a small population multiple factors like gene flow, genetic drift, non random mating etc disturbs the equilibrium or the value of the equation to a large extent.

So, the correct answer is 'The population is small'
