Question

which event occurs twice during meiosis ?​

Answer 1

Meiosis is the process of cell division that results in the formation of daughter cells.

• In the process of meiosis, the diploid cell will be converted to haploid cells. The cells that undergo meiosis are gametic cells.

• Under meiosis, there are two phases or cycles and they are known as Meiosis 1 and Meiosis 2.

• Both the meiosis contains phases like Prophase, Metaphase, Anaphase, Telophase.

• The major difference between the two phases lies in prophase as prophase of meiosis 1 contains additional 5 steps to form chromosomes while prophase of meiosis 2 is similar to mitosis.

• Therefore, during meiosis, the events that occur twice are metaphase, anaphase, and telophase. In the case of prophase 1 and 2, both are completely different.

Answer 2

Meiosis has two cell division cycles thus, cell divide twice in meiosis.

Explanation:

• Meiosis is the process by which a single cell divides twice to produce four cells that contain half of the original genetic information.
• These are our sex cells – in men, sperm, and in women, eggs. During meiosis, one cell divides twice to produce four daughter cells.
• Meiosis has two cell division cycles, which are referred to as Meiosis I and Meiosis II for convenience.
• Meiosis I is the time when the number of chromosomes is cut in half and when crossing over occurs.
• Meiosis II reduces by half the amount of genetic information in each cell's chromosome.
• As a result, four haploid cells (daughter cells) are formed.
• Haploid cells have one set of chromosomes, which is half the number found in diploid cells.
• During each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
