a woman with blood type AB gave birth to a baby with type B blood, two different men claim to be the father, one has type A blood and the other type B. can the genetic evidence decide in favor of either?
Ok..... so you should know that someone with blood group A or B that it could be AA or AO and or BB and BO. Therefore if you do the punnett square. crossing it with AB... you are MOST likely to get an offspring of blood group B with the father of group B, whereas its LEAST likely to get an offspring with father of group A.
