Genetic recombination is the process by which genetic elements contained in two separate genomes are brought together in one unit. This mechanism may enable the organism to carry out some new function and result in adaptation to changing environments. Genetic recombination usually involves much larger changes Entire genes, sets of genes, or even whole chromosomes, are transferred between organismsGenetic recombination is the process by which genetic elements contained in two separate genomes are brought together in one unit.
