High Quality Content by WIKIPEDIA articles! Homologous recombination is a type of genetic recombination in which nucleotide sequences are exchanged between two similar or identical molecules of DNA. It is most widely used by cells to accurately repair harmful breaks that occur on both strands of DNA, known as double-strand breaks. Homologous recombination also produces new combinations of DNA sequences during meiosis, the process by which eukaryotes like animals and many plants make sperm and egg cells. These new combinations of DNA represent genetic variation in offspring, which in turn enables populations to adapt during the course of evolution.
