WebWhat is the significance of chiasma? Significance of chiasmata: - It is very essential to form during cell division because it helps in the attachment of chromosomes to opposite spindles. - If chiasmata present it helps chromosomes to divide properly. - The alignment will happen properly if there is chiasmata during metaphase I of the meiosis.
