E. D. A. B. 11. C. 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. What is the genotype of a man who is normal but whose father had Huntington's disease? What is the genotype of a woman who has Huntington's disease if both of her parents had Huntington's disease? 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? 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? Since Huntington's disease is caused by a dominant allele, does this mean it's also the most common allele in the population? F. Since Huntington's disease is caused by a dominant allele, does this mean that a heterozygote makes more gametes with H than with h? 43

O O c. A person who has a gene allele for a disorder with reduced penetrance (60%) that is transmittedin an autosomal dominant pattern and is usually expressed after age 30 has reached the age of 50 without any manifestations of the disorder. He now states that he wishes that he had decided to have children now that he knows he cannot pass the disorder on to any children he fathered. Is this man's thinking correct? Explain This person is not right because he can still pass the disorder to his offspring. Penetrance is the proportion of individuals carrying a particular variant (or allele) of a gene (the genotype) that also express an associated trait (the phenotype). The individual exhibits signs and symtoms of genetic disorder. He did not develop features of the disorder, the condition is said to have reduced (or incomplete) penetrance. He is a carrier of the allele for this disorder. As carrier he can give the genetic information to his child who could have a complete penetrance and…
3. D. A. B. C. 10. Familial hypercholesterolemia is the most common genetic cause of heart disease. It is caused by a dominant factor (C). The recessive factor (c) produces a protein that processes cholesterol normally and leads to a normal risk for heart disease. Answer the following questions about the inheritance of this disease. What is the phenotype of a woman whose genotype is Cc? What is the genotype of a man who has hypercholesterolemia but whose mother did not have the disease? If a man who is heterozygous for the disease marries a woman who is heterozygous for the disease, what is the chance that any child of theirs will inherit the disease? If a man who is homozygous dominant marries a woman who is homozygous recessive, what would you predict for the the genotypes and phenotypes of their children? If the first 2 children from the marriage described in D above have the disease, what is the chance that a third child would be normal? Explain your answer. 41
