10. There are two allelic variants of IGF2. One is 40 kilodaltons (kD) and the second is 50 kD,and both are detectable in the blood. Fred and Mary both only express the 40 kD protein intheir blood. They have two sons, Bob and Todd, who both only express the 40 kD protein too.Bob's daughter, Jill, expresses the 50 kD protein in her blood. What can you conclude fromthese data?a. Fred and Mary must both be heterozygous for the 50 kD / 40 kD variants.b. Fred must be heterozygous for 50 KD / 40 kD variants; Mary's second allele isunknown.c. Mary must be heterozygous for 50 kD / 40 kD variants; Fred may be homozygous forthe 40 kD.d. Fred must be heterozygous for 50 kD / 40 kD variants; Mary must be homozygous forthe 40 kD.e. Bob is not the biological father of Jill.

2. The common grandfather of two first cousins has hereditary hemochromatosis, a recessive condition causing an abnormal buildup of iron in the body. Neither ofthe cousins has the disease nor do any of their relatives.a. If the first cousins had a child, what is the chancethat the child would have hemochromatosis?Assume that the unrelated, unaffected parents ofthe cousins are not carriers.b. How would your calculation change if you knewthat 1 out of every 10 unaffected people in the population (including the unrelated parents of thesecousins) was a carrier for hemochromatosis?
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.

8. Huntington’s disease is a degenerative disease of the nervous system that strikes in middle age. The allele that causes the disease (H) is dominant to the allele that results in the normal condition (h). Answer the following questions about the inheritance of this disease. A. What is the genotype of a man who is normal but whose father had Huntington’s disease? B. What is the genotype of a woman who has Huntington’s disease if both of her parents had Huntington’s disease? C. If a man who is heterozygous for Huntington’s disease marries a woman who is normal, what would you expect for the genotypes and phenotypes of their children? D. If a normal man marries a woman who is homozygous for Huntington’s disease, what do you expect for the genotypes and phenotypes of their children?

1. A mother with blood type A has a child with blood type O, What is the mother's genotype? 2. A mother with blood type B has a child with blood type O. What are the possible genotype of the father?
The ABO blood groups in humans are expressed as the IAlB, and IAalleles. The allele encodes the A blood group antigen, lBencodes B, and i encodes O. Both A and B are dominant to O. If a heterozygous blood type A parent (IAi) and a heterozygous blood type B parent (IBi) mate, one quarter of their offspring will have AB blood type (IAIB) in which both antigens are expressed equally. Therefore, ABO blood groups are an example of: multiple alleles and incomplete dominance codominance and incomplete dominance incomplete dominance only multiple alleles and codominance
The following pedigree shows the pattern of inheritance of red green color blindness in a family. Females are shown as circles and males as squares; the squares or circles of individuals affected by the trait are filled in red. What is the chance that a son of the third-generation female indicated by the arrow will be color-blind if the father is a normal man? If the father is color-blind?
7. In a disputed parentage case, the child is blood type O, while the mother is blood type A. What blood type would exclude a male from being the father? Would the other blood types prove that a particular male was the father?
