Meiosis is the process through which the genetic material of a diploid germ cell is divided into four haploid gametes -- the resulting gametes are thus NOT genetically identical to the mother cell, unlike what was seen in mitosis. The process involves two nuclear divisions (names meiosis I and meiosis II), each consisting of five stages (interphase, prophase, metaphase, anaphase and telophase). At the end of meiosis, the resulting gametes should now have the proper amount of genetic material to allow them to participate in the process of fertilization with gametes produced by the opposite sex, to form new diploid organisms. The process of meiosis is fundamental to many of the concepts studied in genetics.
