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

Detailed explanation-1: -Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

Detailed explanation-2: -Telophase II and Cytokinesis The chromosomes arrive at opposite poles and begin to decondense. Nuclear envelopes form around the chromosomes. Cytokinesis separates the two cells into four unique haploid cells. At this point, the newly formed nuclei are both haploid.

Detailed explanation-3: -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.

Detailed explanation-4: -Finally, during telophase II, the chromosomes are enclosed in nuclear membranes. Cytokinesis follows, dividing the cytoplasm of the two cells. At the conclusion of meiosis, there are four haploid daughter cells that go on to develop into either sperm or egg cells.
