DNA is never 100% proof. Science admits there is (something like) a 1 in 100 million chance it belongs to someone else with an exact same dna sequence.
No. That’s incorrect.
The only people who will have identical DNA to you are your identical twin or your clone. No one else will ever have identical DNA to you.
Part of your DNA IS your fingerprint…..
That is incorrect. Fingerprints have nothing to do with DNA. In fact, identical twins, who have the same DNA, have different fingerprints.
