There is a dominant trait that affects the short arm of chromosome #4 known as Huntington's disease. A woman that is heterozygous for Huntington's disease and a normal, unaffected male have a female child. What is the probability that this child may be affected by the disease?
Because there are different systems in the body to prevent diseases, however chromosome diseases are usually hereditary so there is about a 50% chance that the child may be affected by this disease.
