4. Consider a pair of monozygotic twins, both are XY individuals (monozygotic = originated from the same zygote). One was healthy and the other showed symptoms of hemophilia related to loss-of-function of F8 (recall F8 locus is on the X chromosome, not in the pseudo autosomal region). a. Propose a way that these two twins have a different F8 phenotype despite arising from the same zygote? b. Consider XX monozygotic twins that came from a zygote that was +/- for the F8 locus. Is it possible that a mitotic non-disjunction could result in one twin developing hemophilia and the other not have hemophilia? Use a drawing to help explain your answer.
