The father of three sons and two daughters begins to show symptoms of Huntington disease. What is the probability that Sam, the man’s second oldest son (II-2), will suffer from the disease if he lives a normal life span? Sam’s mother and her ancestors do not have the disease. Sam's father was adopted, so we do not know his biological family history for Huntington disease. Explore all possible outcomes for Sam and explain your reasoning. What about the risk to Sam's sisters? Would that be the same or not?

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…

They would like to have more children and were told by a friend that since their first child was normal their future children would be normal as well. Explain to them the probability of future offspring being normal or having the disease (assume that this is an autosomal disease). Be sure to tell them whether the disease is brought about by a dominant or recessive allele and what fraction of their children (if any) could be carriers for the disease.arrow_forward
