Gene Flow
Gene flow refers to the transfer of genetic material, such as alleles or genes, between populations of the same species. This can occur through various mechanisms, such as migration of individuals, pollen transfer in plants, or mating between individuals from different populations. Gene flow is an important factor in shaping the genetic diversity and evolution of populations, as it can introduce new genetic variation and homogenize gene pools. It can also play a role in the adaptation of populations to changing environments and in the speciation process.
