Chapter 4, Problem 23PDQ
A husband and wife have normal vision, although both of their fathers are red–green colorblind, an inherited X-linked recessive condition. What is the probability that their first child will be (a) a normal son, (b) a normal daughter, (c) a color-blind son, (d) a color-blind daughter?
