Chapter 13 Mitosis - Somatic Cells - Diploid - 2 Diploids Meiosis - Sex cells - Haploid - 4 Haploid Cells Meiosis 1! - Purpose separate homologous chromosomes (the same, pair of chromosomes) - Prophase 1 - Chromosomes coil and condense - Nuclear Membrane breaks down. - Synapsis - Homologous chromosomes pair - Chiasmata - Sharing of DNA <-- Reason why we all look different - Metaphase 1 - Chromosomes line up on the metaphase plate. - Line up 2 by 2
