Question

Hardy- Weinberg’s principle of ‘Zero evolution’ is based on

• A. All of the above
• B. Selective mating
• C. Genetic equilibrium
• D. Migrations

Answer 1

The correct option is C Genetic equilibrium

Hardy - Weinberg equilibrium states that allele frequency in a given population is always constant from one generation to another. This equilibrium can be affected if the gene pool of the given population is affected due to gene flow, genetic drift, mutations etc. Hardy - Weinberg equilibrium is based on the fact that the gene pool will always remain constant until it gets affected by external forces or in other word it is based on genetic equilibrium.

Selective mating and migrations can affect the allelic frequency, thus disturbing the equilibrium.
