Question

Hardy-Weinberg principle cannot operate if

• A. Population does not interact with other population
• B. Population is large
• C. Frequent mutations occur in population
• D. Free interbreeding among all members

Answer 1

The correct option is C Frequent mutations occur in population

Hardy-Weinberg principle states that the allele frequencies remain constant in successive generations in a population which does not undergo evolutionary change.

Assumptions of Hardy-Weinberg principle are as follows:

• Population should be large.
• There must be random mating.
• No migration.
• No mutation.
• No natural selection.

As mutations bring about change in the gene frequency Hardy-Weinberg principle can not operate if there are frequent mutations in a population.

Hence the correct option is
c. Frequent mutations occur in population
