WebThe chiasmata are thought to be the points where two non-sister chromatids exchange genetic material during chromosomal crossover during meiosis (sister chromatids also form chiasmata between each other, but because their genetic material is identical, it does not cause any change in the resulting daughter cells). WebThe outward movement of chiasmata was termed “chiasma terminalization” (DARmwoN 1929), and the connection remaining was in- terpreted as a single “terminal chiasma”, ir- respective of how many chiasmata had moved to the same end. In those organisms that regularly showed complete terminalization (e.g. Primula
