7. Hereditary ichthyosis in humans is a sex-linked trait. If a normal male and a carrier female produce offspring, what will be the phenotypic ratios of: Normal females to scaly females? Normal males to scaly males? 8. Raedwald is color blind. His four sisters and his parents all have normal color vision. Who passed this condition on to Raedwald, and what can be said for certain about the genotypes of his maternal and paternal grandparents?

1. A mother with blood type A has a child with blood type O, and she claims that Mister X is the father. Mister X denies that he could possibly be the father, because he has blood type B. If you were the judge presiding over this case, which of the following arguments would you find most convincing? a. Mr. X could be the father if his blood genotype is IBIB, and the mother’s blood genotype is IAIA b. Mr. X cannot be the father because a child with blood type O cannot have a parent with blood type B c. Mr. X could be the father if his blood genotype is IBi, and the mother’s blood genotype is IAi d. Mr. X cannot be the father because a parent with blood type B cannot have a child with blood type O e. Mr. X cannot be the father because the human ABO blood types are sex-linked traits 2.
