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.

The suitable gene exchange needs high dispersal potential during life history stages, such as planktonic egg and active migration.

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.

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.

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., 2002).
