Gene Flow Summary
613 words, approx. 2 pages
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 Summary
204 words, approx. 1 pages
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...

Crop Science
An empirical model for pollen-mediated gene flow in wheat.
07/01/2005: 6,692 words, approx. 22 pages
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....

Crop Science
Isolation of maize from pollen-mediated gene flow by time and distance.
11/01/2005: 8,091 words, approx. 27 pages
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...
