Tricky questions?

Just say hypothetically you had a baby to a man who died before he knew the baby existed. You want the baby to know its fathers family but they've never met you before and want to know if the baby is really their grandchild. I know you can prove it with a paternity test but you haven't had one done. Is there a test you can do with the grandparents or his siblings to find out if they are related? Can a DNA test prove the baby is really a part of the family even though the father can't be tested? Also, just say you slept with identical twins and got pregnant. Is there any way of knowing which is the father?

Best Answer - Chosen by Asker: a test can be done with the grandparents and the baby to see if that is their grandchild and no there is no way to determine who is the father with identical twins because the dna is the same
