gene flow
The loss or gain of alleles from a population due to the emigration or immigration of fertile individuals, or the transfer of gametes, between populations.

Gene flow: The exchange of genetic traits between populations by movement of individuals, gametes, or spores. It involves the spread of new variants among different populations through dispersal.
Gene Flow
Many species are made up of local populations whose members tend to breed within the group. Each local population can develop a gene pool distinct from that of other local populations.

Male lions leave the pride where they are born and take over a new pride to mate. This results in gene flow between prides.
Gene flow The movement of alleles from one population into another.
Gene map A diagram of the relative positions of genes within the genome
Gene pool All the alleles at a particular locus present in a population.
Gene flow. The exchange of genes between different but (usually) related populations.
Gene frequency. The percentage of a given allele in a population of organisms. See Allele.
Gene flow
- The movement of genes from one population to another by way of interbreeding of individuals in the two populations
Gene mapping ...
Gene flow moves alleles among populations through interbreeding as well as by migration of breeding individuals. Gene flow increases variation within a population by introducing new alleles produced in another population.
gene flow An exchange of genes between two populations of a species, or in extreme cases, between populations of two species (hybridization).
Gene flow between more distantly related species occurs infrequently. This is called horizontal transfer. One interesting case of this involves genetic elements called P elements.
barriers to gene flow Factors, such as geographic, mechanical, and behavioral isolating mechanisms that restrict gene flow between populations, leading to populations with differing allele frequencies.
(See Dominant gene, Fusion gene, Gene amplification, Gene expression, Gene flow, Gene pool, Gene splicing, Gene translocation, Recessive gene, Regulatory gene.) Gene amplification. The presence of multiple genes.
Gene flow: or gene admixture is the only one of the agents that makes populations closer genetically while building larger gene pools.
Selection, in particular natural selection produced by differential mortality and fertility.
Parapatric speciation. The differentiation into distinct species of populations experiencing some gene flow
Parasite. An organism living on or in, and negatively affecting, another organism ...
people are really concerned about small populations, such as an endangered species, and how do you maintain those small populations-in particular, what are the genetic problems that you run into with small populations, like lack of gene flow and loss ...
Gene flow: the transfer of genes (actually, alleles) from one population to another.
