The creation, by a process of intermolecular exchange, of chromosomes combining genetic information from different sources, typically two genomes of a given species. Site-specific, homologous, transpositional and non-homologous (illegitimate) types of recombination are known. Recombination can be intragenic, between two alleles of a gene (cistron), or intergenic where there is information exchange between non-allelic genes.
Process by which genetic elements in two separate genomes are brought together in one unit.
The occurrence of progeny with combinations of genes other than those that occurred in the parents, owing to independent assortment or crossing over (after King & Stansfield, 1990).
Also, a new strain of a virus that occurs as a result of the breakage and renewal of co-valent links in a nucleic acid chain, so that the nucleic acids are rearranged in the chain....

The formation of new combinations of alleles or new genes which occur when two homologous DNA or chromosomes break and exchange parts.

Recombination: The trading of fragments of genetic material between chromosomes before the egg and sperm cells are created. Key features of recombination include the point-to-point association of paired chromosomes (synapsis) followed by the visible exchange of segments (crossing over) at X-shaped crosspoints (chiasmata). Recombination is the princ...Found on http://www.medterms.com/script/main/art.asp?articlekey=5248
The formation in offspring of combinations of genes not present in either parent. This results from the assortment of chromosomes and their genes during the production of gametes and the subsequent union of different sorts of gametes at fertilization.

In cosmology, recombination refers to the epoch at which charged electrons and protons first became bound to form electrically neutral hydrogen atoms. After the Big Bang, the universe was a hot, dense plasma of photons, electrons, and protons.

The action of a free electron falling back into a hole. Recombination processes are either radiative, where the energy of recombination results in the emission of a photon, or nonradiative, where the energy of recombination is given to a second electron which then relaxes back to its original energy by emitting phonons. Recombination can take place...Found on http://www.encyclo.co.uk/local/21690

The capture of an electron by a positive ion. It is the opposite process to ionization. As the electron drops through the energy levels of the atom with which it has recombined, it gives rise to emission lines that are known as recombination lines at specific wavelengths.Found on http://www.daviddarling.info/encyclopedia/R/recombination.html

In genetics, any process that recombines, or `shuffles`, the genetic material, thus increasing genetic variation in the offspring.
