WebRecombination is a process of producing new combinations of alleles by the recombination of DNA molecules. It is also referred to as genetic recombination, as there is an exchange of genetic material (DNA) … Genetic recombination (also known as genetic reshuffling) is the exchange of genetic material between different organisms which leads to production of offspring with combinations of traits that differ from those found in either parent. In eukaryotes, genetic recombination during meiosis can lead to a novel set of genetic information that can be further passed on from parents to offspring.
