gene exchange

new genetic combinations resulting from the exchange of genes between individuals. In offspring resulting from normal sexual reproduction within a breeding population, the new genetic combinations are formed from genes contributed by both parents.

When a population originates from a small group of founders that bred only with each other, certain genetic variants can become amplified, more so than in a larger starting population with more gene exchange.

Further, the algorithm introduced the outbreeding fusion mechanism into the niche technology, to eliminate the kin individuals, fuse the distantly related individuals, and promote the gene exchange between the excellent individuals from niches.

In this project, I will focus on the accumulation of barriers to gene exchange and the processes underlying increasing reproductive isolation.

Much less gene exchange between kingdoms--plants, animals, and bacteria--that are obviously very different and unrelated.

Though gene exchange across species boundaries is considered infrequent, the researchers observed that haloarchaea living in the Lake's hypersaline environment practice it comparatively often, like neighbors "chewing the fat" in a small-town coffee klatch.

But those who do travel contribute to a healthy gene exchange and sometimes they establish new populations.

In addition, obligate mutualists of insects have low recombination (often complete asexuality), likely due to the loss of recombination genes including the striking loss of recA in some genomes, a lack of mobile DNA and repeated elements, and reduced opportunities for gene exchange within host cells (Mira et al.

The results of our scientific research give us the right to suggest that the most intensive gene exchange occurs with the neighboring populations in the Northwest, North and Northeast of Kazakhstan.

Isolating populations that would normally experience gene exchange can result in a general decline in genetic diversity within a population and a corresponding increase in genetic divergence among different populations.
