What is the primary source of variation in a population?

A

Gene flow

B

Mutation

C

Natural selection

D

Genetic drift

correct option: b

Mutation is the primary source of genetic variation in a population. Mutations are random changes in the DNA sequence of an organism's genes, and they can introduce new alleles or traits into a population.

Gene flow involves the exchange of genetic material between populations, natural selection acts on existing variations, and genetic drift refers to random changes in allele frequencies in a population due to chance events.
