How many meiosis are required for the formation of 200 zygote?

How many meiosis are needed to form a zygote?

Hence, the correct answer is 125 meiosis divisions will be done for the formation of 100 zygotes in humans.

How many meiosis divisions are required to produce 200 male gametes and 200 female gametes respectively WRT higher plants )?

Now, 1 meiotic division in male produces 4 gametes. So, in order to make 200 male gametes, there will be 50 meiotic divisions in male. In total there are 200+50=250 meiotic divisions required to produce 200 seeds.

How many meiosis are required to the formation of 50 zygotes?

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).

How many meiosis are required for the formation of 100 seeds?

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 meiosis are required for the formation of 160 zygote?

Similarly, in females, 1 meiotic division forms 1 female gamete. Hence, total 100 meiotic divisions are essential to form 100 female gametes. Hence, total 125 meiotic divisions are essential for the formation of 100 zygotes in human.

How many meiosis divisions are required for formation of 200 zygotes?

Thus 5 meiotic divisions are needed for the formation of 4 seeds and 250 meiotic divisions are required fro the formation of 200 seeds.

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 meiotic divisions will be required for the formation of 80 zygotes in an Angiospermic plant?

80 male gametes i.e. pollen grains are produced by 20 meiosis in microspore mother cells while 80 female gametes i.e. megaspores are formed by 80 meiosis in megaspores mother cells because in angiosperm plants, after meiotic division in single megaspore mother cell, four megaspores are formed but only one megaspore is …

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.
