• Assertion : According to Hardy – Weinberg Equilibrium, the frequency of an allele remains the same generation after genetation. Reason : The only way to bring about a change is by natural selection.
• A. Genetic drift refers to change in allelic frequencies of a gene pool due to chance and occurs both in large and small populations. R. Small populations will, therefore, suffer more than larger ones.
