Gene flow can be defined as the movement of genes between populations, species, or organisms. For eg., bacteria can transfer genes between different cells.

Gene flow is also called gene migration. Gene flow is the transfer of genetic material from one population to another. Gene flow can take place between two populations of the same species through migration, and is mediated by reproduction and vertical gene transfer from parent to offspring.
