    Meiosis can fail to separate chromosomes at either Meiosis I or meiosis II resulting in aneuploidy. Assume a female has two versions of X chromosomes. The male has one X chromosome and one Y chromosome and they have children with XXY. (Klinefelter's) Evaluate each of the following possibilities as possible or not possible. For any possibilities list all of the combinations of chromosomes that might be present in their child (eg. X^f1, X^f2, Y^m)

    1) A disjunction during meiosis I in the father's sperm production.
    2) A disjunction during meiosis II in the father's sperm production.
    3) A disjunction during meiosis I in the mother's egg production.
    4) A disjunction during meiosis II in the mother's egg production.
