Cite evidence that genetic contributions from both parents are necessary for normal prenatal development.
In Hunter syndrome, lack of the enzyme iduronate sulfate sulfatase leads to buildup of carbohydrates called mucopolysaccharides. In severe cases, this may cause the liver, spleen, and heart to swell. In mild cases, deafness may be the only symptom. A child with this syndrome is also deaf and has unusual facial features. Hunter syndrome is inherited as an X-linked recessive condition. Intellect is usually unimpaired and life span can be normal. A man who has mild Hunter syndrome has a child with a woman who is a carrier.
a. What is the probability that if the child is a boy, it would inherit Hunter syndrome?
b. What is the chance that if the child is a girl, she would inherit Hunter syndrome?
c. What is the chance that a girl would be a carrier?
d. How might a carrier of this condition experience symptoms?
