Meiotic homologous recombination (HR) is important for proper chromosomal segregation during gametogenesis and facilitates evolutionary adaptation via genomic reshuffling. In most eukaryotes, HR is mediated by two recombinases, the ubiquitous RAD51 and the meiosis-specific DMC1. The role of RAD51 in mammalian meiosis is unclear and study of its function is limited due to embryonic lethality of RAD51...
