A person who has a gene allele for a disorder with reduced penetrance (60%) that is transmittedin an autosomal dominant pattern and is usually expressed after age 30 has reached the age of 50 without any manifestations of the disorder. He now states that he wishes that he had decided to have children now that he knows he cannot pass the disorder on to any children he fathered. Is this man's thinking correct? Explain
