@ Hello Nitin @
=============

Here is your answer friend:-------

Megaspore mother cell are diploid which produces four megaspores by meiosis.
And these megaspores are haploid in ploidy.
Out of four only one megaspore will remain functional and so it is called female gametophyte.

Hope it will help you!
Thanks!
