## How many mitotic divisions are required for formation of male gametes?

Hint: To produce 100 male gametes, 25 meiotic divisions are done, and to produce 100 female gametes, 100 meiotic divisions are done. Hence the total divisions which are essential in humans for the formation of 100 zygotes.

## How many meiosis and mitosis are required for the formation of a male gametophyte from a pollen mother cell Microspore mother cell?

2 meiotic and 1 mitotic.

## How many meiosis and mitosis are required for formation of male gametophyte?

Hence, one meiotic division and two mitotic division are required for the formation of fully mature male gametophyte from microspore mother cell in angiosperm.

## How many mitotic divisions are needed for 400 male gametes?

To produce 400 male gametes, we need 100 meiotic divisions. Apart from that, each megaspore mother cell forms one female gamete.
