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.

On the other hand, gene flow between populations also can lead to outbreeding depression; the reduction of fitness following intraspecific hybridization between individuals from spatially separated genetic sources (Barrett and Kohn, 1991).
On the other hand, the reproductive strategy, which includes a pelagic larva would guarantee, in the absence of geographic barriers or restrictive oceanic currents, greater larval dispersal and thus greater gene flow. This might however diminish variability in the population structure (Strathmann 1986, Hunt 1993, Palumbi, 1994, Kyle & Boulding 2000, Collin 2001, Hellberg et al.
