Phenylketonuria (PKU) is a disorder caused by a recessive allele. Two carrier individuals have progeny. Answer the following questions in order and show solutions whenever relevant.
If they have a normal child, what is the probability that he or she will be heterozygous?
If they have three children, what is the probability of having 2 affected children and one normal child?
If the woman (phenotypically normal) in question 5(a) married to a color-blind man and
already had a color-blind son, what is the probability that they will have a color-blind
daughter?
Short Answer. Please provide your final answer as a fraction
