Detailed explanation-1: -Meiosis occurs in all sexually-reproducing single-celled and multicellular organisms (which are all eukaryotes), including animals, plants and fungi. It is an essential process for oogenesis and spermatogenesis.

Detailed explanation-2: -It occurs only in cells in the reproductive structures of organisms. It happens in all tissues except the brain and spinal cord.

Detailed explanation-3: -The given statement is True. Meiosis is a form of cell division that has to take place to bring out the gametes. This type of cell division occurs both in males and females. In males, it happens so that it can give rise to sperms, while in females, it happens to give rise to the ovum or the egg.

Detailed explanation-4: -Mitosis occurs in somatic cells (i.e. all the cells in the body except gametes) and the end results are two genetically identical diploid daughter cells per parent cell. Meiosis occurs only in gametes (i.e. sex cells) and the end results are four genetically unique haploid daughter cells per parent cell.
