Question

Read the following statements and select the correct option.
(i) Increase in melanised moths after industrialisation in Great Britain is a proof for natural selection.
(ii) When more individuals of a population acquire a mean character value, it is called disruption
(iii) Changes in allelic frequency in a population will lead to Hardy-Weinberg equilibrium.
(iv) Genetic drift changes the existing gene or allelic frequency in future generations.

• A. Only (ii) is correct
• B. Only (iv) is correct
• C. Both (i) and (iv) are correct
• D. Both (i) and (iii) are correct

Answer 1

Answer: (C)

Both (i) and (iv) are correct

When more individuals of a population acquire a mean character value, it is called stabilising selection. No change in allelic frequency in a population will lead to Hardy-Weinberg equilibrium.

So, the correct option is 'Option C'.
