Explain following term:
Apomixis
Advertisements
उत्तर
It is the phenomenon of the formation of the embryo(s) through the asexual reproduction method without the formation of gametes and the act of fertilization. Alternatively, it is unusual sexual reproduction where there is no meiosis and syngamy. The embryo develops in the ovule, and the ovule develops to form a seed. In apomixis, when a gametophyte organ or cell produces embryo-like structure without fertilization, it is called apogamy. Similarly, when a diploid sporophyte cell produces a diploid gametophyte without undergoing meiosis, it is called apospory, e.g. Orange, Mango.
