Given two co-dominant alleles (C and D) for the X-linked gene glucose-6-phosphate dehydrogenase. A mother with phenotype C and a father with phenotype D had a son with Klinefelter’s. Assume that the son had the phenotype CD. Indicate whether the non-disjunction occurred in the father or the mother and whether the non-disjunction took place in meiosis I, meiosis II or either. If the son with Klinefelter’s had the C phenotype, how would that change your answer?
