Consider the following information and answer the question that follows:

  • Reshma’s mother is normal, but her father is suffering from PKU.
  • Reshma is suffering from PKU. She has two younger brothers who are identical twins; both are suffering from PKU. Reshma’s two elder sisters are normal.
  • Reshma marries Robert, who is normal. Reshma gives birth to a son named Jason who is normal. After some time, Reshma and Robert have two more children: a daughter with symptoms of PKU and a son without any symptoms of PKU.
