For the production of 200 egg cells how many meiotic divisions are required?
1 50 divisions
2 100 divisions
3 200 divisions
4 400 divisions
Explanation:
1 parent mother cell undergoes meiosis to give rise to 4 egg cells out of which only 1 egg cell is functional. So, technically 1 mother cell produces 1 egg cell. For the production of n egg cells, n meiotic divisions are required. Hence, for 200 egg cells, 200 meiotic divisions are required.

Meiosis, generally results in
1 2 daughter cells
2 4 daughter cells
3 Remains the same
4 All of them are wrong
Explanation:
Meiosis is a process in which a singular diploid cell is divided twice to give rise to four haploid daughter cells.

Meiosis occurs in organisms during
1 Sexual reproduction
2 Vegetative reproduction
3 Both sexual and vegetative reproduction
4 None of the above
Explanation:
The production of offspring by sexual reproduction includes the fusion of two gametes, each with a complete haploid set of chromosomes. Gametes are formed from specialised diploid cells. This specialised kind of cell division that reduces the chromosome number by half results in the production of haploid daughter cells. This kind of division is called meiosis. Meiosis ensures the production of haploid phase in the life cycle of sexually reproducing organisms whereas fertilisation restores the diploid phase. Hence, meiosis is an essential process for sexual reproduction.

In meiosis, the chromosome number
1 Is reduced by half
2 Increases twice
3 Sometimes increases, sometimes decreases
4 None of the above
Explanation:
During meiosis, the chromosome number gets reduced by half. Thus, it leads to the production of haploid daughter cells. The sperm and the egg are haploid cells and when they fuse during fertilisation they produce a diploid cell called zygote.
