Meiosis Diagram
  1. gametes
    1. produce sex cells- egg or sperm
    2. Chromosome number
      1. diploid
        1. cells that contain both sets of homologous chromosomes- 2N
        2. haploid
          1. gametes with a single set of chromosomes- N
        3. Meiosis 1
          1. Interphase 1
            1. DNA replication
            2. Prophase 1
              1. each chromosome pairs with it's correspondent to form a tetrad that consists of 4 chromatids
                1. crossing over
                  1. when the homologous chromosomes form tetrads they exchange portions of their chromatids which produce new combinations of alleles
                2. Metaphase 1
                  1. Anaphase 1
                    1. Telophase 1 & Cytokinesis
                      1. cell separates into 2 haploid cells that are different from each other
                    2. Meiosis II
                      1. the 2 haploid cells produced by meiosis 1 enter meiosis II
                        1. unlike meiosis, neither cell goes through chromosome replication
                          1. each of the cell's chromosomes has 2 chromatids
                            1. Prophase II
                              1. Metaphase II
                                1. Anaphase II
                                  1. Telophase II & Cytokinesis
                                    1. results in 4 haploid daughter cells- N
                                      1. each containing unreplicated chromosomes
                                    2. female
                                      1. results in 1 egg
                                        1. other 3 (polar bodies) aren't involved in reproduction
                                        2. male
                                          1. results in 4 equal-sized gametes called sperm
