Question
Genetic drift is a change in the allele frequency of a population due to ______________.
- Random chance
- Natural selection
- Non-random mating
- Artificial selection
Hint:
Genetic drift is a change in allele frequencies in a population from generation to generation.
The correct answer is: Random chance
Genetic drift is a change in allele frequencies in a population from generation to generation that occurs due to chance events. To be more exact, genetic drift is change due to "sampling error" in selecting the alleles for the next generation from the gene pool of the current generation.
Hence, Random Chance is the correct answer.
