The chances of proving non-paternity, when the type of the falsely accused man is known, were calculated. In New York City the average chances of proving non-paternity by means of all four agglutinogens, A, B, M, and N are approximately one in three. A man of type A++ has less than one chance in ten to prove his innocence, and a man of type B++ has only one chance in seven.
