2(a) Red-green color blindness is inherited as a recessive X-linked trait. What is the probability that a woman with phenotypically normal parents and a color-blind brother will have a color- blind son? Assume that she has no previous children. 2(b)If the woman (phenotypically normal) in question 2(a) already had a color-blind son, what is the probability that the next child of the phenotypically normal woman will have a color- blind son? Short Answer. Please provide your final answer as a fraction Answer 2b only
