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?

4. Mr. Salazar has Type A blood while Mrs. Salazar has Type B. They have four children. Bobbie has Type A, Gabbie has Type B, Alex has Type AB, and Teddie has Type O. What are the genotypes of all six people in this family? NOTE: The ABO blood type gene has three alleles. IA and IB are codominant; i (for Type O) is recessive to both.

O. exal B. Heredity Assume that dominant allele is B (brown eye color) and that recessive allele is b (blue eye color). Genotype of the father (male) is BB. Genotype of the mother (female) is Bb, Questions: 7. List all the possible genotypes and phenotypes and calculate the probability of each. 8. What is the probability of this couple having a child with brown eyes? What about blue eyes? Add Tip omment ASK Question Dow 5,288 66 APR 28 étv 260
