Studies have shown gene flow
provides an avenue for the transfer of genes from cultivated to natural populations (Burke et al.
facilitate such gene flow
and further argues for stream capture across
Third, we investigated patterns of gene flow
to determine if the Sumgayit region is acting as an ecological sink.
However, the time since expansion indicated from the mismatch distribution ([approximately equal to]200,000 - 450,000 years ago) would seem too long for genetic divergence not to have arisen, assuming there has been no gene flow
among localities and that effective population sizes are even one-tenth to one-hundredth of the current estimated census size of 7-20 million individuals.

and cross pollination were studied at 53 forage maize trials across the UK in a range of climatic conditions and its central conclusion was that a separation distance of only 24.
The three agencies would each publish a new set of guidance documents, which do not carry the force of law, outlining how to prevent or minimize gene flow
from experimental crops, thus ensuring that no unapproved proteins enter the food chain.
Therefore, the apparent correlation observed between genetic and geographic distances among the populations suggests that the data conform to an isolation-by-distance model of gene flow
, and this model (isolation-by-distance) is suitable for investigating marine distribution (Palumbi 2003).
is an age-old process that is well understood by farmers, who grow hundreds of crops, virtually all of which have been genetically improved in some way with a variety of techniques.
25 signifies that there is sufficient gene flow
between localities to negate the effects of genetic drift.
First, that spined soldier bugs from the geographically distant field locations have greater genetic variation compared to laboratory colonies; second, that individuals from different field samples have a high degree of genetic variation and gene flow
between locations; and, third, that laboratory reared colonies will retain genetic diversity despite restricted gene flow
indicus populations (RC and ND) with some level of gene flow
between the breeds.
