The blood groups of the men, the children and their mother were as follows: Person ABO group MN series Rhesus factor Husband O M Rh+ Lover AB MN Rh- Wife A N Rh+ First child O MN Rh+ Second child A N Rh+ Third child A MN Rh- The ABO and Rh types are no help here. But, the husband cannot be the father of the 2nd child. The husband is MM, and the 2nd child is NN. Therefore the child's father contributed an N to that child, but the husband does not have an N to contribute. The other children could be from either man. |
