7. The Case of the Suspected Father: Blood typing is often used as evidence in paternity cases in courts, but it cannot be used to convict a man, only exonerate him (show that he is not the father!). In a series of disputed paternity cases, the mother and child each had the blood types listed in the table below. For each, indicate the blood types (phenotypes!) which, if found, would exonerate (free) an accused man. Mother's Phenotype Possible Genotypes for Mother Child's Phenotype Possible Genotypes for Child Man exonerated if he has these phenotype(s) A AB A AB B. B. 8. Give the Ratios of the following crosses: Phenotypic Ratio Genotypic Ratio Example Monohybrid Cross Dihybrid Cross Not needed Incomplete Dominance Co - Dominance Epistasis Not needed B.

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.

4. Marfan syndrome is a genetic trait caused by in a dominant allele. The trait causes a weakening of the aorta that can be fatal.

9. The factors for normal hemoglobin (S) and sickle-cell hemoglobin (s) are considered codominants: heterozygous individuals have some normal red blood cells and some sickle cells but are not considered to have the disease. A heterozygote is said to have the sickle-cell trait but not the disease. A. What is the genotype of a man with the sickle-cell trait? B. If normal man marries a heterozygous woman, what do you expect for the genotypes and phenotypes of their children? C. If 2 heterozygous people marry and have 3 children who don’t have the disease, what is the chance that their fourth child will have the disease? D. Assume that medical science finds a treatment for sickle-cell anemia so that people with the disease can live out a normal life span but their genes are not changed. If 2 people are saved from the effects of the disease, marry, and have children, what would you expect for the genotypes and phenotypes of their children? Would the children…

The genotypes of their children are: ss, Ss, SS, ss, Ss, Ss, and SS. What must the genotypes of both parents be? Your answer should include a Punnett square to illustrate your work, and list all the genotypes and phenotypes.
