Question

What's the difference between genetic drift and change due to natural selection?
0/5
Genetic drift does not require the presence of variation.
Genetic drift does not involve competition between members of a species.

Genetic drift never occurs in nature, natural selection does.
There is no difference.

Answer 1

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.
