gene flow

During summer, low water levels cut off gene flow between these two.

Physical barriers to gene flow are usually, but not always, natural.

See below for environmental risks of gene flow among plants.

"I'm sure we'll find records of places where similar genes flowed in the past."

Such gene flow is less likely today because the populations are more separated.

The study also found that there is limited gene flow between the populations.

This will allow species to increase gene flow and help with migration.

Or is base running a societal metaphor for gene flow?

Female choice can also play a role in hindering gene flow.

Thus novel genes flow from either side into the hybrid zone.

The investigators exclude any significant gene flow between the two islands.

Gene flow is the transfer of alleles from one population to another.

Until the agricultural revolution 10,000 years ago, people used to live in small populations with little gene flow between them.

Barriers to gene flow need not always be physical.

It is not known when gene flow between the subspecies ceased.

However, more complicated forms of gene flow are present in this genus.

Gene flow - The movement of genes from one population to another by individuals moving between the populations.

"This shows that corridors, yes, do maintain some gene flow."

Variation of this kind is homogeneous, due to factors such as gene flow.

"Gene flow is not this juggernaut evolutionary force that some people might make it out to be," he said.

Gene flow between individuals and over ecological gradients has been studied.

If there was some gene flow between the populations, these adaptations could spread to the rest of the species.

No evidence for gene flow in the direction from modern humans to Neanderthals was found.

Other reports, also published between 1995 and 2007 find that there was gene flow from many migratory populations.

Population genetic models can be used to reconstruct the history of gene flow between populations.
