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.
