Explanation:
got it right
Meiosis is the reductional division which takes place in organisms which reproduce by the process of sexual reproduction. It produces haploid cells to maintain the chromosome number constant in the offpsring.
Meiosis is a type of cell division which results in the reduction of chromosome number in the cell by half of its original number. Meiosis is also known as reductional division.
Meiosis takes place in the process of formation of gametes in the organisms which reproduce by sexual mode of reproduction. In meiosis, four daughter cells are produced, which are haploid. The male and female gametes produced by meiosis under fertilization to form zygote which is diploid. If the gametes were not haploid then the offspring will show presence of extra set of chromosome which can lead to chromosomal disorders.

Answer:
The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell. "Meiosis is reductional," said M.
