Mother’s genotype: IAIA & Father’s genotype: IBIB D. Mother’s genotype: IAi & Father’s genotype: IBi

If the granddaughter III-1, has a girl, what is the chance that the girl will have the allele for breast cancer?

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?

Q15: A research team interested in mapping human genes discovered a new restriction length polymorphism (RFLP). The nature of the polymorphism is shown in the figure below: RESEARCH METHOD GAATTC CTTAAG GACTTC CTCAAG GAA CT TTC AAG GAGTTC CTCAAG Long fragments Short fragments Туре 1 homozygote Туре 2 homozygote Heterozygote S First, they test the RFLP in a family with the pedigree below. The individuals colored blue are affected by hemophelia, a blood clotting disease. а. Dad Mom daughter1 daughter2 son1 son1 b. Next, they genotyped (determined the RFLP polymorphism, type 1 or type 2) of daughter1's family with the results shown below: husband daughter1 ||
