    (i)  Why asexual reproduction does not produce the genetic variability?
    (ii) Banana is a parthenocarpic fruit whereas oranges show polyembryony. How are they different from each other with respect to seeds?

    Answer:

    (i)  Asexual reproduction does not produce the genetic variability because only mitotic division occurs during asexual reproduction.
    (ii) Banana develops from an ovary without fertilization having non-viable seeds so it is called a parthenocarpic fruit. An orange contains seeds with more than one embryo, thus it shows polyembryony.
