Gene flow is the transfer of genetic material between separate populations. Many organisms are divided into separate populations that have restricted contact with each other, possibly leading to reproductive isolation. Many things can fragment a...

Gene flow is the movement of genes within and among populations. Gene flow is a major force in evolution that can act to increase or decrease the types and numbers of genes available to a local breeding group. One type of gene flow occurs whenever...

Gene flow is the movement of genes within a population. This movement of genes is the product of mating and gene exchange within populations. A genetically isolated population is known as a deme, gene flow can occur within demes or between demes when...

In population genetics, gene flow (also known as gene migration) is the transfer of alleles of genes from one population to another. Migration into or out of a population may be responsible for a marked change in allele frequencies (the proportion of...

The extent of pollen-mediated gene flow (PMGF) in wheat (Triticum spp. L) as a function of distance from a pollinator source has been measured in recent field studies. Wheat is primarily self-pollinated; however, some cross-pollination can occur depending on biological, agronomic, and environmental factors....

Development of improved genetic traits in maize (Zea mays L.) requires robust measures to prevent pollen-mediated gene flow (PMGF) and assure isolation of new traits, whether these traits are the result of conventional breeding or of modern genetic techniques. Studies were conducted in California...
