Re: My craziest thought ever
[ QUOTE ]
My chain of thought was brough on after reading that there was a 1 in 6.5 billion chance of a false positive in DNA crime scene matching. So, I took that to mean that there are 6.5bn different permutations of DNA - is that correct, and if so, what would someone with my identical DNA look like?

No, the reason that there's a small chance of a false positive is because they don't check the entire strand of DNA. Two humans will have the majority of their DNA the same, except for small areas of reapeating sequences. The chances that two people randomly have the exact same DNA is waaaaaaaaaaaaaaaaaaay higher.
