WebJun 8, 2024 · Animals experience gene flow when individuals leave a family group or herd to join other populations. The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population. Mutations are changes to an organism’s DNA that create diversity within a population by introducing new alleles.
