The tendency of population to remain in genetic equilibrium may be disturbed by

A lack of mutations
B lack of random mating
C random mating
D lack of migration.

Verified Solution

Answer & Solution

Correct Answer

(B) lack of random mating

Step-by-step Solution

Detailed explanation

(b) : Hardy-Weinberg law states that allele frequencies in a population are stable and remain constant from generation to generation when there is random and nonselective mating. In case of lack of random mating, genetic equilibrium maybe disturbed.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
