Webb4 dec. 2024 · Answer: Prophase-I of meiosis has five sub-stages namely Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis. In pachytene exchange of genetic material between non-sister chromatids takes place through crossing over and chiasma formation which does not occur in prophase of mitosis.

WebbAs prophase 1 continues, the chromosomes coil up further, a spindle forms, and the homologous pairs are moved toward the centre of the cell. Metaphase 1.
