Let's say there's a mother with blood type A and the baby is type B; the list of possible fathers drops because in order for that baby's blood type to be B, it would have to come from someone with either AB, or B.

Hope this helps!

You can only dis-prove that someone is the father, based on their blood type. Using a 'punnett square' should help.

If you are trying to prove to your family that you are not the biological father of a baby what can you do?

The only absolute proof would be a blood test. A blood test cannot prove you are the father, but it can prove that you aren't. In other words, a blood test could give what doctors call a "false positive," but if the test comes out negative, it's a sure thing -- you aren't the father. But a blood test requires a sample from the baby, as well, for comparison with yours. If the child's parent won't consent, a blood test isn't possible. One other thought: in the US, a person is considered innocent until proven guilty. That means it's not up to you to prove your innocence. It's up to your family to prove your guilt. Do they have any real reason to suspect you?
