If a deaf child is born to hearing parents, both parents must be Dd. The child of a deaf man and a DD hearing woman will definitely have hearing. The child of a Dd father and Dd mother has a 50% chance of having hearing. If the first two children from Dd parents are deaf, there is no risk that their next child will also be deaf. If a deaf man and a hearing woman have a deaf child, the mother’s genotype must be Dd.1. True2. False
