For the following crosses, determine as accurately as possible the genotypes of each parent, the parent in whom nondisjunction occurs, and whether nondisjunction takes place in the first or second meiotic division.
both color blindness and hemophilia, a blood-clotting disorder, are x-linked recessive traits. capital letters represent wild-type alleles, lowercase letters represent mutant alleles. in each case, assume the parents have normal karyotypes.
part a
a man and a woman who each have wild-type phenotypes have a son with klinefelter syndrome (xxy) who has hemophilia. what are the genotypes of the parents?
select at least two answers (one genotype for the father and one genotype for the mother). if there is more than one possible genotype for a parent, select all that apply.
