Question

The tendency of a large population to remain in genetic equilibrium can n be disturbed by

• A. Presence of random mating
• B. Lack of gene migration
• C. Lack of mutations
• D. Presence of selective mating

Answer 1

The correct option is D Presence of selective mating

For a population to be in Hardy-Weinberg equilibrium five conditions must be met :

1. Population must be very large.

2. Population must be isolated from other populations (no immigration or emigration).

3. No mutations

4. Random mating

5. No natural selection

Non-random/selective/assortative mating causes more expression of recessive phenotypes.

So, the correct option is 'Presence of selective mating'.
