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

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?
