NEET BIOLOGY

Detailed explanation-1: -The cell membrane starts pinching inward to form two separate cells. A second cell division follows: The copies of the chromosomes separate. So the parent (original) cell gives rise to four sex cells. The nucleus of each sex cell contains half of the original genetic material.

Detailed explanation-2: -Meiosis Consists of a Reduction Division and an Equational Division. Two divisions, meiosis I and meiosis II, are required to produce gametes (Figure 3).

Detailed explanation-3: -As soon as the cytoplasm divides, meiosis is complete. There are now four daughter cells-two from each of the two cells that entered meiosis II-and each daughter cell has half the normal number of chromosomes (Figure 7).

Detailed explanation-4: -In humans, the haploid cells made in meiosis are sperm and eggs. When a sperm and an egg join in fertilization, the two haploid sets of chromosomes form a complete diploid set: a new genome.

Detailed explanation-5: -During meiosis one cell? divides twice to form four daughter cells. These four daughter cells only have half the number of chromosomes? of the parent cell – they are haploid. Meiosis produces our sex cells or gametes? (eggs in females and sperm in males).
