I looked it up.
Q. Do identical twins have the exact same dna?
A. Since no one has ever sequenced identical twins' dna, no one knows for sure, said terry spear, a supervisor at the california criminalistics institute and an authority on dna testing.
``even if, starting as embryos, they had identical dna, there is some chance that in utero there might have been mutations in their dna,'' she said. ``after the dna is in two separate embryos, there's a fairly reasonable chance that some of that dna will change through the course of mutation.
So the answer. Who knows lol. I'd try testing though, because there is a chance that the dna is seperate.
