Question

The change in the allele frequencies takes place 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

The allele and genotype frequencies in a large population remain constant if the population is randomly mating and if factors responsible for evolution are absent. Mutations, gene flow, genetic drift and natural selection are evolutionary forces that bring about evolution. Random mating prevents speciation and maintains the allelic frequency. Thus, the correct answer is option D.
