What Produces Gene Flow

Question

What produces gene flow?
A) mating between populations
B) geographical isolation
C) mutation
D) speciation

Accepted Answer

Gene flow is the movement of genes from one population to another. This can occur through mating between populations, which introduces new genetic variations into the gene pool. Geographical isolation and speciation can limit or prevent gene flow, while mutation is a source of genetic variation within a population, but does not directly produce gene flow.
