My friend has a baby and knows that the dad who wants a DNA test isn’t the dad. Now the normal thing to do would be to tell the truth but he wants to do a test and has ordered one through the post. She’s thinking about swabbing her own mouth as she reckons because obviously she’s his mum that this will come back showing this, so then she can make out that he is the dad if this makes sense? Would this even work? Surely the two peoples dna are different?
