A family in which club foot was inherited as an autosomal dominant trait. They discovered a mutation in the PITXI gene that caused club foot in this family. Through DNA testing, they determined that 11 people in the family carried the PITXI mutation, but only 8 of these people had club foot. Which of the following is the correct interpretation of the observation?
