gene exchange

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.

This finding is consistent with the amount of gene exchange among partial subgroups that would be expected based on the ecological environment in which F.
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.
In lowland and Tibetan chicken populations, distinct gene exchange (Gst = 0.01, Nm = 25.21; Gst = 0.05, Nm = 4.9) was detected between White-Tianfu (lowland chickens) and Haiyan and Doilungdeeqeen (Tibetan chickens).
In the normal gene exchange involved in the hybridization of varieties of plants and breeds of animals, tens of thousands of genes belonging to both male and female parents are all randomly mixed-up.

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., 2002).
