For the formation of 20 microspores and 20 functional megaspores how many meiosis are required?

1 micropore mother cell undergoes meiosis to form 4 haploid microspores.20 microspore formation requires 20/4=5 meiosis1 megaspore mother cell produces 1functional megaspore by meiosisTherefore, for formation of 20 functional megaspores 20 meiosis will be required.
