To determine:
On the basis of pedigree: a. The most likely mode of inheritance for Nance-Horan syndrome. b. The probability of another child of couple III-7 and III-8 to have Nance-Horan syndrome. c. The probability that one of the children of III-2 and III-7 would have Nance-Horan syndrome.
Introduction:
