Detailed explanation-1: -Meiosis is a process that occurs in sex cells, such as sperm and egg cells in the human body, to make more of them. In the primordial germ cells of males and females, meiosis takes place in the testes and ovaries, respectively.

Detailed explanation-2: -Meiosis is the process of cell division that occurs in the testes and ovaries and results in the formation of the reproductive cells, the sperm and the ovum. In meiosis four ‘daughter cells’ are formed after two rounds of division.

Detailed explanation-3: -In multicellular plants and animals, however, meiosis is restricted to the germ cells, where it is key to sexual reproduction. Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).

Detailed explanation-4: -In both the developing ovary and the testis, germ cells undergo mitotic proliferation prenatally, but the time of entry into meiosis and the duration of meiosis are strikingly different between the sexes.

Detailed explanation-5: -In males, meiosis occurs during spermatogenesis in the seminiferous tubules of the testicles. Meiosis during spermatogenesis is specific to a type of cell called spermatocytes, which will later mature to become spermatozoa. Meiosis of primordial germ cells happens at the time of puberty, much later than in females.
