This page lists UNSW Embryology content related to meiosis, a form of cell division only occurring in haploid gamete development.
Meiosis is the cell division that occurs only in production of germ cells where there is a reduction in the number of chromosomes (diploid to haploid) which is the basis of sexual reproduction. Note all other non-germ cells divide by mitosis.
- meiosis I - (MI) The first part of meiosis resulting in separation of homologous chromosomes, in humans producing two haploid cells (N chromosomes, 23), a reductional division. Phases: Prophase I - Metaphase I - Anaphase I - Telophase I
- meiosis II - (MII) The second part of meiosis. In male human spermatogenesis, producing of four haploid cells (23 chromosomes, 1N) from the two haploid cells (23 chromosomes, 1N), each of the chromosomes consisting of two sister chromatids produced in meiosis I. In female human oogenesis, only a single haploid cell (23 chromosomes, 1N) is produced. Phases: Prophase II - Metaphase II - Anaphase II - Telophase II
