Genetic drift operates in : -
A
Small isolated population
B
Large isolated population
C
Fast reproductive population
D
Slow reproductive population
Detailed Solution
Genetic drift is the random change in allele frequencies due to chance (sampling error) from one generation to the next.
In a large population, chance effects average out. In a small, isolated population, only a few individuals breed, so chance can greatly change allele frequencies; some alleles may be lost or fixed.
Examples are the founder effect and the bottleneck effect.
So genetic drift operates in a small isolated population.
