Give scientific reasons : Genetic drift is much more likely to change allele frequencies in a small population rather than large population.

Option A

Option B

Option C

Option D

Solution

If a population is sufficiently large, chance events are unlikely to alter the overall gene frequency. In small population, however only few organisms may carry certain alleles chance event could reduce or even eliminate such alleles from the population.
