Cell division occurs in two main forms namely; mitosis and meiosis. Mitosis increases the number of cells by cell division. It helps in replacing the worn out cells, in healing of wounds and in early stages of gonadal cell multiplication. This process occurs in four stages such as prophase, metaphase, anaphase and telophase. After undergoing the four phases of mitosis a cell divides into two daughter cells which are the duplicate copy of the mother cell. The reproductive cells divide by the process of meiosis. There are two major phases of meiosis i.e. meiosis -I and meiosis-II. After undergoing meiosis-I two daughter cells are formed which contain different genetic component and have half the number of chromosome from the mother cell. Following meiosis-I the daughter cells undergo meiosis-II which forms four daughter cells which are smaller in size as compared to the mother cell and they all have different genetic components from that of mother cell and as well as from each other.
