Question

Read the statements (i-iv) and choose the correct option:
i. Increase in melanized moths after industrialization in Great Britain is a proof of Natural Selection.
ii. More individuals acquiring mean character value cause disruption.
iii. Change in allelic frequency leads to Hardy-Weinberg equilibrium.
iv. Genetic drift changes allelic frequency in future generations.

• A. ii is correct
• B. iv is correct
• C. i and iv are correct
• D. ii and iv are correct

Answer 1

Answer: (C)

i and iv are correct

1. Industrial melanisation leading to the reversal in proportion of white and dark-winged moth is an example of evolution by natural selection.

2. More individuals acquiring mean character value causes stabilization.

3. Change in Allelic frequency distrupts Hardy-Weinberg equilibrium.

4. Various factors capable of changing allelic frequency are Gene migration or gene flow, Genetic drift, Mutation, Genetic recombination, Natural selection.

So, the correct option is 'i and iv are correct'.
