Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell. Meiosis produces four gamete cells. Meiosis is required to produce egg and sperm cells for sexual reproduction.
Though meiosis reduces the number of parent cells by half, the cells are restored in the offspring after the sperm and the egg unite according to Scitable by Nature Foundation. Meiosis I is the first meiotic division, which begins with prophase I. The complex of DNA and protein, which is known as chromatin, condenses to form chromosomes. Meiosis II is a mitotic division of the haploid cells produced in meiosis I. After meiosis is complete, there are four haploid daughter cells that eventually become sperm or egg cells.
