Essay

Huntington's disease, an often fatal disease of the central nervous system, is inherited from a dominant allele. Furthermore, a person may not show symptoms of the disease until 30 - 50 years of age.

Assuming that Jane does not have the disease, determine the probability that one of the children will eventually have Huntington's. What is the probability that both Joe and Jane will inherit the disease?
