Question

Hardy-Weinberg principle states that, allele frequencies get change when evolutionary forces act on a population. Which of the following is not an evolutionary force?

• A. Mutations
• B. Gene flow
• C. Genetic drift
• D. Random mating
• E. Natural selection

Answer 1

The correct option is D Random mating

According to the Hardy Weinberg law, the allele frequencies, irrespective of their dominance of recessiveness, in a population remain constant under absence of factors responsible for evolution (natural selection, migration, genetic drift, mutation and gene flow). A simple genetic equilibrium occurs in a population if the population is large, has random mating, and has negligible effects of above mentioned evolutionary forces. Correct answer is D.
