Question
Assertion: Hardy-Weinberg principle states that in the absence of disturbing influences, gene frequencies of large populations of sexually reproducing organisms do not change, provided that matings, occur at random.
Reason: The disturbing influences include mutation, gene flow, genetic drift, genetic recombination and natural selection.

Solution
The correct option is B Both assertion and reason are true but reason is not the correct explanation of assertion
The Hardy-Weinberg principle law states that in an infinitely large, interbreeding population in which mating is random and in which there is no selection, migration, or mutation, gene and genotype frequencies will remain constant from generation to generation.
The disturbance influences are mutation, gene flow, genetic drift, genetic recombination and natural selection. Disturbance in Hardy- Weinberg equilibrium, i.e., change of frequency of alleles in a population would then be interpreted as resulting in evolution.
