Mitosis: 5 stages. Prophase = chromosomes condense and become visible. Prometaphase Spindle forms and Sister chromatids attach to microtubules from opposite centrosomes. Metaphase Chromosomes align @ equator. Anaphase Sister Chromatids Seperate and move to opposite Poles. Telophase chromosomes decondense and are enclosed two nucler. During Meiosis 1: Crossing over occurs. Nondisjunction = mistakes in chromosome segregation d uring meiosis I or 11. Go actively going through mitosis. = Duplication Occurs. Meiosis 1 (no dupl.) Meiosis 11 Gametogenesis the formation of gametes.
