A key player behind parental chromosome matching during meiosis

Researchers have clarified how homologous chromosome pairing — a process necessary for sperm and egg formation where paternally- and maternally-derived chromosomes match and exchange genetic information during meiosis — attracts factors that play a monitoring role. Since details on the genetic information exchange mechanism during meiosis have not yet been clarified, this research may lead to future advances in reproductive medicine, such as the identification of the causes of infertility.
