4 0

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.
