The correct answer is 1/2 or one-half.

Since the father has additional fingers and toes, he is likely to pass it down to his daughter or son, whereas their mother is normal, which does not have any abnormalities in the number of toes and fingers, which is why their offspring has 1/2 chance that he or she may acquire his or her father's trait.
