Analysis of Autosomal Recessive and Dominant Traits Huntington disease is a rare, fatal disease that usually develops in the fourth or fifth decade of life. It is caused by a single autosomal dominant allele. A phenotypically normal man in his twenties who has a 2-year-old son of his own learns that his father has developed Huntington disease. What is the probability that he himself will develop the disease? What is the chance that his young son will eventually develop the disease?

the Mode of Inheritance (MOI) exercises. Focus on determining the values in the colored cells. Your solutions should read as prose, not simply computations. I have provided values for two MOIs discussed in the lecture, Autosomal Dominant MOI, and X-linked Recessive where the father is affected and the mother is homozygous unaffected. Sometimes, there is confusion regarding defining the disease allele and wild-type allele for a specific mode of inheritance. In this worksheet, you'll note that the D allele is the disease allele for the Autosomal Dominant mode of inheritance. However, it is also the disease allele for the Sex-Linked Recessive mode of inheritance, where the father is affected. The point is, any letter or symbol can represent a disease allele or wild-type allele as long as you define its meaning. For example, I may use r to be the disease allele in an Autosomal Recessive mode of inheritance, and R to be the wild-type allele, or vice versa, as long as I write something like:…
