Sentences with phrase «gene flow processes»

Not exact matches

Previous studies have looked mainly at genes causing atherosclerosis and genes affecting the function of platelets and clotting processes as risk factors for ischemic stroke (clot obstructing blood flow to the brain).

We call this process «speciation with gene flow,» and evolutionary biologists have long wondered if the genetic basis for this process is highly repeatable and if the genes involved are spread out across the whole genome or in a few discrete regions.»

«Gene flow is then an important component in fully understanding speciation processes and particularly in the recent evolution of hominids,» he said.

How important is gene flow for maintaining a species» identity and diversity, and what are the implications of these processes for evolution, conservation of endangered species, invasiveness, or unintentional gene flow from domesticated crops to wild relatives?

The gene encodes an enzyme that breaks down prostaglandins, hormonelike molecules that promote inflammation and help regulate fluid balance and blood flow — processes that could affect clubbing.

Allopatric speciation holds that species with large central populations are stabilized by their large volume and the process gene flow.

Our approach to identifying islands of divergence relies, in part, in levels of variation within populations and therefore is potentially sensitive to any process that reduces diversity within either subspecies, and thus high divergence may not be directly associated with signatures of reduced gene flow due to incompatibilities.

Gene flow between commercial and native varieties is a natural process that has been occurring for many decades.»
