gene flow


Also found in: Dictionary, Encyclopedia, Wikipedia.

gene flow

changes over time in the genetic composition of a population as a result of migration rather than of mutation and selection.

gene flow

n.
Transfer of genes from one population to another, as by migration or the dispersal of seeds and pollen.

gene flow

The movement of genes from one group of organisms to another.

gene flow

or

gene migration

the movement of genes from one organism/ population to another.

If gene flow is limited by dispersal of cysts by wind, as Graham and Wirth (2008) argued, we expected to see a fairly sharp increase in divergence among populations beyond some relatively short distance.
Limitation of using male sterility, gene silencing and cleistogamy is because they are not completely effective and some gene flow can still occur.
Our data suggest the degree of gene flow between both social forms, though mediated exclusively by males, may be more tenuous for S.
In the in situ model, the steepness of the ecotones yields different levels of isolation between neighboring populations as a result of natural selection rather than restricted gene flow at a geographic barrier.
In the present study we investigated the genetic variability, gene flow, genetic exchange and migration in mosquito populations from urban and rural areas of Sialkot, Punjab, using random amplified polymorphic DNA (RAPD) technique.
Peripheral populations are less likely to receive immigrants whereas the core populations typically occupy prime habitat and experience greater levels of gene flow (Hoffmann and Blows 1994, Brown et al.
The percentage of gene flow will increase every passing year.
Studies of adaptation and gene flow in the ocean have been especially useful and interesting because many marine species have broad geographic ranges (e.
Gene flow is also impacted by the size of populations, the distance between them, and the landscapes around their fragmented habitats (Young et al.
Two other models involved multiple dispersals, with both involving routes along Arabian Peninsula's northern and southern ends - one involved connections and gene flow between these routes, and the other did not.
The second part discusses an assortment of topics, including symbiogenesis, cognitive ecology, genetic draft, genomic conflict, avian evolutionary genomics, elevational gradients, cytonuclear genomic interactions, molecular phylogenetics of Australian flora, introgression of crop alleles, facilitation, assisted gene flow, the genus Spartina, diversification on islands, mate choice, thermal ecology, diversity and competition, ecosystem collapse in the face of climate change, conservation biology, forest lepidoptera, biomass distribution of forests, and symbiont transmission.
