What is the simple meaning of genetic drift?
Answer and explanation
Correct answer: Random change in trait frequency in a small population
Genetic drift is a change in the frequency of inherited traits caused by chance rather than by a trait’s usefulness. Its effect is especially strong in a small population, where the accidental survival or reproduction of only a few individuals can alter the proportion of alleles in later generations. Thus, option A is correct. Options B, C, and D describe food movement, evaporation, and blood clotting, which are unrelated biological processes.
