A. Selection for average traits
B. When a population splits in two
C. A mutation becoming more common
D. Genes moving between two populations



Answer :

Final answer:

Gene flow involves the exchange of genes between populations, influencing allele frequencies and introducing genetic variation.


Explanation:

Gene flow is the exchange of genes between populations or species, leading to the movement of alleles from one population to another. It occurs through migration of individuals or gametes, impacting allele frequencies and introducing new genetic variation. Gene flow can affect evolutionary changes, including the potential for the evolution of new species.
