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.

Awoman whose sister tested positive for a specific mutation in the brca1 gene, which increases the risk for breast and ovarian cancer, is found not to have that mutation but does have a mutation of unknown significance near the known mutation site. how should this woman be counseled? select one: a. she should be informed that her risk for breast cancer is greater than the general population but not as great as her sister’s risk. b. she should be informed that because she does not have the mutation, her risk for breast cancer is not greater than that of the general population. c. she should be informed of her gene mutation status and be presented with all the available prophylaxis options and reconstruction options. d. she should be informed that she does not have the specific mutation but that because another mutation is present she should be vigilant about screening
