Mitosis and Meiosis

    What is the difference between the images of Meiosis Metaphase 2 and Mitosis Metaphase other than the fact that the chromosomes have crossed over regions.

    Bad answer:
    In meiosis you have one half of the number of chromosomes, all of the chromosome pairs moved apart from one another. In mitosis each chromosome duplicated itself, so you have the same number of chromosomes you started with. Meiosis you end up with one half of the number of chromosomes

    Example humans:
    start: one cell 46 chromosomes -> 2 cells with 46 chromosomes each This is mitosis.
    start: one cell 46 chromosomes -> 2 cells with 23 chromosomes each This is meiosis.

    oops I get what you are asking. In Meiosis II you have a gamete undergoing mitosis, so one half of the chromosomes are there at the metaphase plate.

    No but you are not given the number of chromosomes. You are just told that the height of the sister chromatids is different

    Please. Do us all a favor: paste the entire question so we all can see it. I do not see the word chromatid in your first post for example.
