Answer:
Genetic drift does not require the presence of variation.
Explanation:
Genetic drift is the random changes to the frequency of an allele in a given population.
Natural selection is the process whereby organisms that are well adapted to the conditions in an environment can survive and produce more offspring.
- Genetic drift does not require variation to occur.
- It usually occurs even when there is less to no variation.
- Natural selection occurs when variation is very large.
- A highly varied gene pool causes natural selection.
