Question

Which of the following is called a reduction division in the formation of new cells?
A. Meiosis
B. Mitosis
C. Cytokinesis
D. None of the above

Answer 1

Hint: In this stage the chromosome number reduces from 46 chromosomes to 23 chromosomes. It is the type of eukaryotic cell division that produces haploid sex cells or gametes from diploid cells.

Complete answer: The mechanism of meiosis includes two divisions in the genetic material.
Meiosis I is a reduction division. The original diploid cell had two copies of each chromosome; the newly created haploid cells had one copy of each chromosome. It reduces the number of chromosomes from 46 chromosomes to 23 chromosomes or 2n to n.
Mitosis is a type of eukaryotic cell division that produces two daughter cells with the same genetic component as the parent cells. The chromosomes replicated during the S phase are distributed in such a way as to ensure that each daughter cell gets a copy of each chromosome. The entire process takes about an hour to successfully separate the animal cells.
Cytokinesis is a structural phenomenon of cell division that can divide the cytoplasm of the parent cell into 2 daughter cells. It happens at the same time as two forms of nuclear division called mitosis and meiosis occurring in animal cells.

Additional information: A cell cycle is a sequence of events occurring in a cell as it grows and divides. It is a sequence of events that occurs in a cell and allows it to be separated into 2 daughter cells.
1. The cell cycle is classified into two main phases that overlap with each other:
the interphase, during which the cell grows, prepares for mitosis and duplicates its DNA, and the mitotic (M) phase, in which the cell divides into two genetically identical daughter cells. 2. Mitosis is the mechanism by which the nucleus of the eukaryotic cell divides.
3. Throughout this cycle, the sister chromatids separate from each other and move to the opposite cell poles.
4. Interphase is classified into three phases: G1, S and G2.
5. The subsequent mitotic (M) phase consists of two processes: mitosis, the process of nuclear division, and cytokinesis, the division of the cytoplasm of the cell.
6. Growing mitotic process can form 2 genetically identical cells.

Thus, the right answer is option A. i.e., Meiosis.

Note: Mitosis and meiosis are the two types of cell division.
Mitosis is the method of creating new cells in the body. Meiosis is the phenomenon that produces egg cells and sperm cells. Cell division is a part of the cell cycle.
