Question: How many meiotic divisions are required for the formation of 200 male gametes?

How many meiotic divisions are required for the 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.

How many meiotic divisions are necessary for formation of 180 sperms?

The number of ‘meiotic divisions’ that are necessary for the production of 80 sperms is 20. Explanation: During the process of spermatogenesis, the haploid sperms are produced by the meiotic division that occurs. The diploid sperm mother cells undergo reduction division or meiosis to form haploid sperm cells.

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 reduction divisions are necessary for the formation of 400 grains of wheat?

Four meiotic divisions are required for the formation of four oospheres and only one meiotic division for the formation of four male gametes. Thus 5 meiotic divisions are needed for the formation of 4 seeds and 500 meiotic divisions are required for the formation of 400 seeds.

How many minimum meiotic divisions are necessary?

Each microspore mother cell or pollen mother cell (PMC) on reduction division (meiosis) gives rise to 4 pollen grains. Hence, to form 100 pollen grains, 25 meiotic divisions are required.

How many minimum meiotic divisions are?

Thus, the correct answer is option (D) 63.

How many minimum meiotic divisions are essential for the formation of 128 zygotes in human?

Thus, the correct answer is ‘125. ‘

How many meiotic divisions are required for the formation of 100 functional pollen grains and 100 functional Megaspores respectively?

So, for the development of 100 megaspores 100 meiotic division is required. – So, by the fusion of 100 microspores and 100 megaspores, 100 seeds are formed. – Hence for the 100 seed production 200 meiotic division takes place in the Cyperaceae family. Hence, the correct answer is option (D).

How many mitotic divisions are needed for 100 cells?

Thus, in all 200 meiotic divisions are required to produce 100 seeds.

How many meiotic division are required for the formation of 100 grains?

So, for the formation of 100 grains of wheat, a total of 100 female gametes are needed, which means a total of 100 meiotic divisions are needed. Hence, including the number of meiotic divisions in both the male and female sex organs of the plant, a total of 125 divisions would give rise to 100 wheat grains.
