Question

Genetic drift operates in

• A. Large isolated population
• B. Small isolated population
• C. Slow reproductive population
• D. Fast reproductive population

Answer 1

The correct option is B

Small isolated population

The difference in the relative frequency of different genotypes in a small population, leading to the chance of disappearance of particular genes, is said to be a genetic drift.

All populations experience drift, but the smaller the population, the sooner the drift will have a drastic effect.
