chiasma(a junction point between non-sister chromatids at the first diplotene of meiosis, the consequence of a crossing over event between maternally- and paternally-derived chromatids; a chiasma also serves a mechanical function and is essential for normal equatorial alignment at the meiotic metaphase in many species; the frequency of chiasmata is very variable between species)
