Then you conclude that IT IS A PERFECT MATCH, because your JURY doesn't know how many you didn't check. Because 12 of the first 13 matched because they would have matched DAMON,BRENDA, or the boys. The first 5 might have matched everyone in the US.
I am not a DNA testing expert, it would be nice if someone with more knowledge of these procedures could explain what 12 of 13 means. How many markers are there?
Interesting statement. Can you imagine two pre-teen boys living next door to an unlocked motor home and not going inside to play or at least check it out? Or even to have a scuffle and leave blood on the floor? Has anyone quesitoned that? How close a DNA match would they be to Danielle?
Tens of thousands. Initial guesses were in the range of 60,000.
Lastest guessamites says under 20,000. Each "marker" is a combo of 4 nucletides (A,C,G,T) n^2 -n, or (4 x 4) -4 == 12 possible combinations.
That's how you get the one-in-a-quadrillion numbers.
Matching 12 in 13 is very stong, match 13 of 13 is a killer.
'course, None of this means anything if the samples were "salted" ...
