-This process produces new genetic variation within a species.
A)Mutation
B)gene flow
C)genetic drift
D)natural selection

Question

Quizplus · Accepted Answer

Mutation is a process that creates new genetic variation within a species by introducing new alleles or changing existing ones. This is the only process among the four listed that directly produces new genetic variation. Gene flow can introduce new alleles from other populations, but it does not create new variation. Genetic drift and natural selection act on existing variation, but do not generate new alleles.
