In the first generation, the man is unaffected and the woman is affected. Individuals indicated by letters in subsequent generations may or may not be affected. Choose your answer carefully since you will receive credit only if you select all possible correct answers. Which individuals, if any, should be carriers of this trait, but not effected (100% chance of being carriers)? If none of the individuals has a 100% chance of being a carrier then select "Q". A B C D E F G H I J K L M N O P Q
