93. The pedigree below shows the sex-linked recessive inheritance of Nance-Horan syndrome, a rare Mendelian disorder in which affected persons have cataracts and abnormally shaped teeth. What is the probability that the first child of IV-6 and V-3 would have Nance-Horan syndrome? Iv A) 114 B) 1/2 C) 1/8 D) 3/16 E) 3/4
