Genetic recombination is the process by which a strand of the genetic material (usually DNA; but can also be RNA) is broken and then joined to the end of a different DNA molecule.

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).

Bacteria can accomplish genetic recombination in three ways. Conjugation, shown in Figures 11 and 12, is the process where one bacterium passes DNA to another through a tube (the sex pilus) that temporarily joins the two conjugating cells.

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.

Homologous recombination is a type of genetic recombination that occurs during meiosis (the formation of egg and sperm cells).

Chiasma (plural chiasmata) Literally a cross. The point at which a genetic recombination event has occurred, visible as a cross-over in meiotic prophase.

The paired chromosomes are called bivalents, and the formation of chiasmata caused by genetic recombination becomes apparent. Chromosomal condensation allows these to be viewed in the microscope.

An agent that causes a permanent genetic change in a cell. Does not include changes occurring during normal genetic recombination.
