Ok...first and foremost I plead complete ignorance - I have not tried any of these calculations myself, so I can not confirm how valid they are, but this is the example I found. I erased the names to protect the "innocent". I hope this helps. Also, at the end of this example, there is also a link to the DNA Fingerprint site where Thomas Krahn does a calculation using population frequencies. I've pasted the link below.
The email begins:
I sent the results of my DNATribes lab test to the person who heads up the Puerto Rican genealogical project, Dra. Ana ..., and asked for her opinion. Below is her response.
From: Dra. Ana ..., MD
Your aSTRs were run against a population of other populations with
For instance Chinese 3.64E+10 is 3.64 x 10 the 10th power. This
However, I believe as [is stated] below that there is not adequate
Here the person tries the calculations for himself:
"I did the math as she explained above, but for the Yupik (Alaska) for whom I got the highest score in the OmniPop and for the score that OmniPop gave for my markers compared to Thai, because the Thai were the highest match DNATribes gave me. (see all scores below)
Yupik (Alaska) (60) 5.71E+10 is 3.64 x 10 the 10th power. This turns
I'm 1.5X more likely to be from the Yupik vs. the Chinese population.
That's more like it. ..."
*The emailer's OmniPop 150.5 top ten results:
Chinese (15) 3.64E+10
End of email
If you decide to try out these out - I hope you'll post your findings:0)
