General Information
Term reciprocal meiotic recombination ID (Ontology) GO:0007131 (Gene Ontology)
Definition The cell cycle process in which double strand breaks are formed and repaired through a single or double Holliday junction intermediate. This results in the equal exchange of genetic material between non-sister chromatids in a pair of homologous chromosomes. These reciprocal recombinant products ensure the proper segregation of homologous chromosomes during meiosis I and create genetic diversity.[ PubMed:2087779 ]
Also Known As"gene conversion with reciprocal crossover"
