Diplotene | The term proposed by von Winiwarter (1900), originally as an adjective, to describe the nuclei at a particular stage of prophase 1 of meiosis when the two chromosomes making up each homologous pair have separated from one another except at nodes (chiasmata) distributed along their length. The successive loops between the chiasmata all lie in one plane. (Gk. diploos, double; taenia, ribbon.) |
