4. Brown eyes are dominant over blue eyes. This is NOT a sex-linked trait. Cross a brown-eyed colorblind male (whose mother had blue eyes) with a normal blue-eyed female (whose father was colorblind). a) What is the genotype of the male? b) What is the genotype of the female? c) What is the probability of getting offspring that are blue-eyed carrier females?

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.
