#13 Meiosis




Meiosis produces gametes which are female egg cells or male sperm cells. Meiosis and mitosis are similar in that they have the G-1 phase, S-phase, G-2 phase and they make duplicate cells. Also, DNA coils tightly into chromosomes during prophase. They differ in that meiosis occurs two times before the process is done and meiosis reduces the number of chromosomes in a cell. Mitosis makes one identical copy. Meiosis has snyapsis which is where each homologous pair of chromosome in meiosis in a tetrad.
