Annabeth and Percy are concerned about having a child with Niemann - Pick disease, which causes abnormal accumulation of fat in cells. This condition, which is very rare, has affected Annabeth's niece (her brother's daughter) and Percy's aunt (his father's sister ). No one else in either family has the condition. What is the probability Annabeth and Percy's first child will have the disease?

Fred, a male, is affected with Lalaphobia. Fred's father is also affected with Lalaphobia; but his mother is unaffected. Fred marries Ginger (a female), who is unaffected, and they have four children: An affected son An unaffected son An affected daughter An unaffected daughter Ginger is pregnant with a fifth child, a son. What is the probability that this son will be affected by Lalaphobia? Assume Lalaphobia is a rare disease. Your answer should be a whole number between 0 and 100. For example, if you enter 33, it means you think there is 33% chance that the son will be affected by Lalaphobia.

Hereditary hemochromatosis is an autosomal recessive genetic disorder that causes the body to absorb too much iron from the diet. This excess iron is stored in the body's tissues and organs, particularly the skin, heart, liver, pancreas, and joints. Because humans cannot increase the excretion of iron, excess iron can overload and eventually damage tissues and organs. A young couple, Bart and Jenny, are expecting a child and are aware there might be a chance that their child could be affected by this disorder. Jenny (the wife) has ichthyosis, but Bart (her husband) is unaffected and completely normal with respect to the allele responsible for this disorder. Both Bart and Jenny were Biology majors as undergraduates. Knowing a little about the pattern of X-linked recessive inheritance, Bart and Jenny were concerned when ultrasound revealed that they would be having a son. However, genetic testing performed on the baby shortly after birth revealed that their newborn son, Mark, did not…
