## 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 mitotic divisions are required for formation of male gametes from a mature male gametophyte?

After pollination, the generative cell after entering into the pollen tube divide Mitotically to form two non-motile male gametes. 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 meiosis and mitosis are required for the formation of 400 male gametes in rice plant?

One meiotic division produces 4 male gametes, so for the formation of 400 male gametes 100 meiotic divisions are required.

## How many mitotic divisions are required for the formation of female gametophyte?

Thus, one meiotic division produces one matured female gametophyte in an angiosperm. Hence, 101 meiotic divisions are required to produce 101 female gametophytes in an angiosperm.

## How many mitotic divisions are required for the formation of?

Correct answer is 8. There are two formulas: 1. Number of mitotic divisions required for formation of n number of cells is n-1.

## How many mitotic divisions are required for the formation of mature embryo sac?

Gamete Formation

From the remaining functional megaspore, the megagametophyte (also known as female gametophyte or embryo sac) develops by three mitotic divisions, at the mature stage consisting of 8 nuclei and 7 cells (one egg cell, two synergids, one central cell and three antipodals).

## How many divisions are required to produce 128 gametes?

Gametes are produced by meiosis. In meiosis 4 cells are formed from one cell. Thus 32 divisions are formed are needed to produce 128 gametes that is 32×4=128.

## How many mitotic divisions are required for formation of 52 cells?

For 50 zygotes, 50 male and 50 female gametes are required. Therefore, 13 meiotic divisions during spermatogenesis produce 52 sperms and 50 meiotic divisions during oogenesis produces 50 eggs. Hence, the correct answer is option (B).
