Homework Help: No. of disjunctions during meiosis

  1. Jul 10, 2004 #1
    I'm trying to work out the number of disjunctions that occur during meiosis. I think during anaphase 2 there are 23 X 2 (where the chromatids disjunction) but... I don't know if the sex chromosomes disjunction, because this is how my textbook defines disjunction:

    in meiosis, separation of homologous chromosomes or of the strangs (chromatids) of replicated chromosomes to opposite poles.

    and I didn't think sex chromosomes were homologous.
    But when I visualise it, it seems to make sense that they do. Any help would be appreciated!
