Question

Meiosis occurs in
A.Haploid cells
B.Mostly haploid cells but occasionally diploid cells
C.Diploid cells
D.Mostly diploid cells but occasional haploid cells.

Answer 1

Hint: Meiosis is a special type of cell division in sexually reproducing organisms. This type of division takes place in the cells to develop gametes such as egg cells and sperm. There are two stages of division resulting in four cells.

Complete answer: 1.Meiosis is a special type of cell division in which one cell divides two times to develop four haploid cells. The cells that are produced contain the original genetic information in half amount and also they are genetically different from the parent cell that gave rise to them.
2.The process of meiosis occurs in all single-celled and multicellular eukaryotes reproducing sexually including plants, animals, and fungi.
3.The production of gametes or sex cells (sperm in males and eggs in females) takes place through meiosis. When there is a fusion of sperm and egg cells, these two haploid cells develop a diploid set of chromosomes giving a rise to a new genome.
4.Therefore, in meiosis, diploid cells (one that has two sets of chromosomes or 2n) gets divided to become haploid cells (having one set of chromosomes or n). Any error in the process of meiosis will lead to abnormalities, aneuploidy, disabilities, etc.
So, the correct answer to the above question is an option (C) i.e. Diploid cells.

Note:Meiosis is known as a reduction division in which the diploid cells get divided two times to produce haploid cells ( division from 2n to n). This division occurs in germ cells to produce male and female gametes. All sexually reproducing organisms undergo meiosis.
