7. Dentinogenesis imperfecta is a rare, autosomal, dominantly inherited disease
(disease is caused by a dominant allele) of the teeth that occurs in about one in
8000 people. The teeth are somewhat brown in color and the crowns wear down
rapidly. Assume that a male with dentinogenesis imperfecta and no family history
of the disease marries a woman with normal teeth. What is the probability that
their first child will have dentinogenesis imperfecta?
