Hint: Meiosis, the process by which sexually reproducing organisms produce gametes (sex cells), is a prerequisite for the embryo's correct development. Humans rely on meiosis to provide a number of critical roles as sexually reproducing, diploid, multicellular eukaryotes, including the promotion of genetic diversity and the production of favourable reproductive circumstances.
Complete answer:
Meiosis is a process that occurs in a female's ovaries. During oogenesis, or the development of mature female gametes or eggs, primary oocytes go through meiosis. During embryonic development, oogenesis begins. The division of primary oocytes is stopped at this time when they reach prophase I. Only before ovulation is Meiosis I completed, resulting in a secondary oocyte.
When a series of diploid cells enter meiosis I during the foetal stage in females, meiosis begins. The process comes to a halt after the end of meiosis I, and the cells congregate in the ovaries. Meiosis resumes during puberty. Each month, one cell from the end of meiosis I enters meiosis II. Meiosis II produces a single egg cell per cycle (the other meiotic cells disintegrate). Each haploid egg cell includes 23 chromosomes.
The fertilised egg cell has 46 chromosomes, or 23 pairs, due to the combination of the egg cell and the sperm cell. The diploid number of chromosomes is restored via fertilisation.The fertilized egg cell, a diploid, is a zygote. Further divisions of the zygote by mitosis eventually yield a complete human being.
Therefore, Meiosis occurs in the female ovary. Ovaries are organs in the female reproductive system.
Note:-
Spermatogenesis closely resembles meiosis than oogenesis, primarily because it is a continuous process that produces four gametes per spermatocyte once it begins (human males begin making sperm at the onset of puberty in their early teens) (the male germ cell that enters meiosis). The important characteristic in males is that spermatogenesis begins at adolescence and continues until senility (till old age or till death).
