3. MEIOSIS MITOSIS 4 haploid cells 2 diploid cells

4. Prophase I Homologous chromosomes pair up in tetrads Tetrad = 4 Chromatids across

5. Metaphase I Tetrads line up along metaphase plate Tetrad = 4 Chromatids across

6. Chromosomes separate and cytokinesis occurs

8. MEIOSIS MITOSIS 4 haploid cells 2 diploid cells
