Answer:
Gene flow is partially responsible for <u><em>genetic variation</em></u>.
Explanation:
In ecology, gene flow can be described as the transfer of genes from one population of a species to another population of a species. Gene flow will result in the changing of the allele frequency of a population. As a result of gene flow, there will be more genetic variation among the population. Gene flow is also termed as gene migration. The gene flow causes the gene pool of a population to change.
