Mitosis Name_________________________________ 1. An onion has a diploid number of 16. How many chromosomes are visible in a cell in Anaphase ? (1 pt) 2. Can you view individual chromosomes during Interphase ? Why or why not ? (1 pt) 3. Determine the approximate relative lengths of the stages of mitosis by looking in the mitotic region and counting the number of cells currently in each stage of mitosis (count at least 50 mitotic cells total). Don't count Interphase cells in your data – they are not mitotic.
