Male gametophytes are formed by the meiosis of a single microspore mother cell whereas in case of formation of female gametophyte, the process is different at the end. A single megaspore mother cell undergoes meiosis to form 4 megaspore, out of which 3 degenerate and only one survives. This surviving megaspore undergoes 3 rounds of mitotic divisions to form the female gametophyte inside the ovule.
