Question
In 1995, doctors reported a Chinese family in which
retinitis pigmentosa (progressive degeneration of the
retina leading to blindness) affected only males. All
six sons of affected males were affected, but all of the
five daughters of affected males (and all of the
children of these daughters) were unaffected.
a. What is the likelihood that this form of retinitis
pigmentosa is due to an autosomal mutation
showing complete dominance?
b. What other possibilities could explain the inheritance of retinitis pigmentosa in this family? Which
of these possibilities do you think is most likely?
