Genetic recombination


Genetic recombination is the transmission-genetic process by which the combinations of alleles observed at different loci (plural of locus) in two parental individuals become shuffled in offspring individuals.

Genetic recombination
The process by which a fragment of DNA from one molecule (chromosome, plasmid, phage genome) is exchanged with or integrated into another molecule to produce a recombinant molecule(s).

Gene map -- the linear arrangement of mutable sites on a chromosome as deduced from genetic recombination experiments. Gene therapy -- addition of a functional gene or group of genes to a cell by gene insertion to correct an hereditary disease.

Holliday intermediate An intermediate in genetic recombination in which two double-stranded DNA molecules are joined by virtue of a reciprocal crossover involving one strand of each molecule.

During the formation of sperm and egg cells, a process of genetic recombination -- or "crossing over" -- occurs in which pieces of genetic material are swapped between paired chromosomes.

In sexually reproducing organisms, genetic recombination is the realloc ation of alleles and chromosomes.

Furthermore, mutations may have little phenotypic effect in isolation but create new traits when combined in an organism through genetic recombination.

The Aviemore model of genetic recombination, in contrast to the double-strand break model, invokes invasion of a duplex by a single strand end resulting in a single Holliday structure.

Organisms that are no longer closely related may have retained the ability for genetic recombination with each other through sex. This is not a derived characteristic. Because of this it is invalid for defining monophyletic taxa.
