Color blindness in humans is one example of a recessive X-linked trait. In a family in which there are two children, a son and a daughter, the daughter is color-blind but the son has normal vision. Which of the following could you most likely conclude about the mother and / or father of this family? a. The father has normal vision b. The mother has normal vision c. Both the mother and the father are color blind. d. Neither parent is color-blind.
