Homologous recombination
Homologous recombination occurs in meiosis. It is a process where a section of DNA is rearranged and put together in a new combination between two pairs of chromosomes which usually occurs at the same point on the chromosome. This recombination will lead to a crossing-over of genes and increases genetic variation as it produces a genetically different DNA as the one it began with. Homologous recombination is important in cells as it is crucial in the support for the recovery of DNA damage.
