Question

The tendency of population to remain in genetic equilibrium may be disturbed by _________.

• A. Random mating
• B. Lack of migration
• C. Lack of mutations
• D. Lack of random mating

Answer 1

The correct option is D Lack of random mating

• The Hardy-Weinberg principle provides the mathematical framework for genetic equilibrium. Genetic equilibrium describes the condition of an allele or genotype in a gene pool (such as a population) where the frequency does not change from generation to generation.
• Genetic equilibrium describes a theoretical state that is the basis for determining whether and in what ways populations may deviate from it.
• The Hardy-Weinberg equilibrium can be disturbed by a number of forces, including mutations, natural selection, non-random mating, genetic drift, and gene flow (immigration, emigration, or migration).

Hence, the lack of random mating will lead to disturbance in genetic equilibrium.
