I remember hearing in class a while back that twins shares the same DNA.
And watching MAURY got me thinking, what if the girl slept with two guys who are twins and got pregnant. Will they be able to determind which one is the father?
The DNA of identical twins is the same. If she slept with two identical twins and got pregnant by one, it would be a hard case to determine the paternity in this example - you'd pretty much have to try and figure out the exact moment of conception and go from there.
Not true, they have different DNA.
