A couple has one child with bilateral retinoblastoma. The mother is free from cancer, but the father has unilateral retinoblastoma and he has a brother who has bilateral retinoblastoma. a. If the couple has another child, what is the probability that this next child will have retinoblastoma? b. If the next child has retinoblastoma, is it likely to be bilateral or unilateral? c. Explain why the father’s case of retinoblastoma is unilateral, whereas his son’s and brother’s cases are bilateral.

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. Symptoms of hereditary hemochromatosis include fatigue, joint pain, arthritis, diabetes, heart disease, skin discoloration, delayed puberty in males, and premature menopause in women. All of these symptoms result a single mutation in a specific gene. Name and define this genetic phenomenon and explain how it relates to this specific genetic situation described above.

Pancreatic cancer is clearly inherited as an autosomal dominant trait in the family illustrated in Figure 23.1.
