How many meiotic divisions are needed for 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.

How many meiotic divisions are required for the formation of 120 seeds?

1 meiotic division refers to the formation of 4 microspores from one microspore mother cell. Each microspore develops into a pollen grain( male gamete). So, for getting 120 male gametes, we require= 120/4 = 30 meiotic divisions.

How many meiotic divisions are required for the formation of 100 seed?

25 meiotic divisions
One meiotic division in a pollen mother cell gives rise to 4 microspores, which develop into 4 pollen grains, therefore 25 meiotic divisions are required to produce 100 pollen grains.

How many meiotic divisions are required for the formation of 64 pollen grains?

16 pollen
Each pollen mother cell (PMC), by a meiotic division, gives rise to a group of four haploid microspores. Thus, 16 pollen mother cells undergo meiotic divisions to produce 64 pollen grains.

How many minimum meiotic divisions are necessary?

Hence the total divisions which are essential in humans for the formation of 100 zygotes. Complete answer: For the formation of one hundred Zygotes a hundred twenty-five meiotic divisions are needed.

How many minimum meiotic divisions are?

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

How do you determine the number of meiotic divisions?

For calculating no. of meiotic divisions the formula is n+n/4 where n is given no. of seeds, zygote, offsprings. =250 meiotic divisions.

How many meiotic divisions are required to produce 100 grains seeds of wheat and Cyperus respectively?

Thus, for producing 100 seeds 100 division in 100 microspore mother cells and 100 divisons in 100 megaspore mother cells will take place. Thus, in all 200 meiotic divisons are required to produce 100 seeds.

How many meiotic divisions are required to produce 200 seeds?

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. Is there an error in this question or solution?

How many gametes are required for the formation of 400 seeds?

For the formation of 400 seeds in the pea plant, we require 400 male and 400 female gametes. In one meiotic division, one microspore mother cell in the anther forms 4 microspores, each of which develops as a pollen grain. For the production of 400 male gametes, the number of meiotic division is 400/4= 100.

How many gametes are required for meiosis to occur?

During sexual reproduction in angiosperms, meiosis occurs in microspore and megaspore mother cells. For the formation of 400 seeds in the pea plant, we require 400 male and 400 female gametes. In one meiotic division, one microspore mother cell in the anther forms 4 microspores, each of which develops as a pollen grain.

How many pollens are required to produce 50 seeds?

Seed comprises of both zygote and endosperm. Thus, in an angiosperm plant in order to produce 50 seeds the requirement will be 50 pollen (each producing two sperms) and 50 ovules (each producing one egg nucleus and one secondary nucleus). The pollens will develop from pollen mother cell and ovules will develop from megaspore mother cell.
