Detailed explanation-1: -Definition. Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes (the sex cells, or egg and sperm). In humans, body (or somatic) cells are diploid, containing two sets of chromosomes (one from each parent).

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: -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-4: -Mitosis is important for sexual reproduction indirectly. It allows the sexually reproducing organism to grow and develop from a single cell into a sexually mature individual. This allows organisms to continue to reproduce through the generations.

Detailed explanation-5: -Meiosis does not occur during asexual reproduction. Meiosis is the process of producing gametes (eggs and sperm). Mitosis, on the other hand, is simply the process of cell division.
