Detailed explanation-1: -Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

Detailed explanation-2: -Only sexually reproductive organisms utilize meiosis. The role of the process is to produce sex cells and to repair genetic defects in germ line cells (the sex cells). Both sexual and asexual organisms go through the process of mitosis.

Detailed explanation-3: -Mitosis is a phase of the cell cycle in which a cell’s nucleus is divided into two nuclei, each with an equal quantity of genetic material. It is an asexual reproductive process that occurs in unicellular organisms. Thus, mitosis is a type of cell division that occurs during the asexual reproduction process.

Detailed explanation-4: -Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.

Detailed explanation-5: -Sexual reproduction requires that organisms produce cells that can fuse during fertilization to produce offspring. In most animals, meiosis is used to produce haploid eggs and sperm from diploid parent cells so that the fusion of an egg and sperm produces a diploid zygote.
