Bob has Klinefelter syndrome and is colorblind (an X-linked recessive condition). His mother and father have normal color vision, but his maternal grandfather is colorblind. Assume that Bob's condition (Klinefelter syndrome) arose from non-disjunction in meiosis in one of his parents. In which parent and in which meirotic division (I or II) did the non-disjunction occur? Explain using diagrams of meiotic divisions ot support your explanation.
