How prophase-I of meiosis differs from prophase of mitosis in an essential way? Describe how it affects the daughter cells?

उत्तर
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. As a result, the daughter cells have a variation in their genetic composition contrary to identical daughter cells of mitosis.
