How many times in meiosis does the cell divide (cytokinesis)?
A
2
B
4
C
3
D
1
Explanation: 

Detailed explanation-1: -Cells go through four stages during each round of division: prophase, metaphase, anaphase, and telophase. Thus, the cells divide two times during meiosis.

Detailed explanation-2: -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).

Detailed explanation-3: -In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense. Cytokinesis splits the chromosome sets into new cells, forming the final products of meiosis: four haploid cells in which each chromosome has just one chromatid.

Detailed explanation-4: -In meiosis, a single cell divides twice to produce four daughter cells. These daughter cells or sex cells have exactly half the genetic material of normal gametes. Meiosis necessitates two divisions since it produces a haploid cell with half the amount of chromosomes. Thus meiosis occurs twice.

Detailed explanation-5: -The division of cytoplasm that occurs in both types of cell divisions i.e. mitosis and meiosis is called cytokinesis.
