How Does Gene Flow Affect the Genetic Composition in Populations

How does gene flow affect the genetic composition in populations?

A) Gene flow promotes genetic diversity by introducing new alleles into populations.
B) Gene flow tends to make the allele frequencies in neighboring populations more similar to each other.
C) Gene flow promotes genetic diversity by introducing new alleles into populations and gene flow . tends to make the allele frequencies in neighboring populations more similar to each other.
D) Gene flow promotes genetic similarities by removing alleles from a population.
