In a situation where two normal parents produce a child with PKU. This means that both parents are heterozygous for the condition i.e Pp × Pp. Hence, the heterozygous male (Pp) will produce gametes in the following proportion: P (1/2) and p (1/2).
This means that the probability that a sperm from the father will contain the PKU allele (p) is 1/2 or 50%
