Question

genetic drift
multiple choice
○ changes genetic variation in a population.
○ has no effect on the genetic variation in a population.
○ causes extinction in a population.
○ makes a population more genetically similar to other populations.

Explanation:

Genetic drift is a random change in allele frequencies within a population, which reduces or alters genetic variation over time. It does not directly cause extinction, nor does it make populations more similar to others; in fact, it can make them more genetically distinct.

Answer:

changes genetic variation in a population.
