Where you you getting your numbers and how are you doing your math? The odds of two random profiles matching perfectly at all 13 loci are about 1 in 10e15. That means you would need a database of just 37 million people before you had a 50% chance of finding a match. At 96 million there would be a 99% chance of at least two people matching (and probably many more). And most places aren't even looking at all 13 loci.Sorry, Nasor, that's not what the ratio means. 1:150 million means there will be only TWO complete matches in 300 million records.
That's just about the total population of the U.S. and is why they chose the limited sequence that is currently being used. That is with a GOOD sample, though, not a partial. (And I know about the "birthday problem.)
