Karyotypes are most closely ociated with..?

The closest answer is e, although I am not a fan of the wording of the question. A karyotype is simply a picture of the chromosomes in a cell during metaphase of mitosis with the chromosomes arranged in order so that you can see the different chromosome pairs easily. You can see certain chromosomal abnormalities using an ysis of a karyotype and so would be able to see an XXY, XYY or XO non-disjunction situation.
