More 20th Dynasty DNA

Here is what came out when I put the DNA of Ramesses III and his son into a popaffiliator program.  It requires 9 loci and I had only 8 to work with.  Therefore in the case of Ramesses III, I added D3S1358, putting in the highest number for the modern Egyptian population, 15, for the father and the arbitrary high Greek one of 16 for the mother.  I did this because, at D7S820, the mother of Ramesses III has 15, which is not even on the chart for modern Egyptians.  Here is the result:


You'll have to click on the image to read it.  Next comes "Unknown Man E".  For his 9th locus, I added a different one, D851179.  For his father, I put the highest number at that marker in the Egyptian population, which is 14.  For the mother, I put in an only slightly lower one of 12.  I added nothing foreign, that I know of, to the DNA of "Unknown Man E", yet his "Eurasian" quotient rises from that of Ramesses III.  Caveat, I do not know how accurate this popaffiliator is.


It can be found here, if anyone wants to enter his own DNA to test it out.

To further check the validity of popAffiliator (I also used version 2 as it is a bit more accurate) (http://cracs.fc.up.pt/~nf/popaffiliator2/) using the same 9 STRs, I ran the STRs of a few samples from DNATribes website (http://www.dnatribes.com/sampleresults.html).

As we can see below, ALL of them were assigned to their correct Continental groups (Sub-Saharan Africa, Eurasia, Asia).

Just note these are NOT admixture proportions but just probabilities. So it seems that even 8 markers are enough to assign the correct continental groups with Sub-Saharan individuals always getting a Sub-Saharan probability > 90%.

9 STRS used(CSF1PO,D2S1338, D7S820, D3S1358,D13S317, D16S539, D18S51, D21S11, FGA)

Ramses III:

Sub-Saharan Africa 96.2%
Eurasia 2%
Asia 1.8%

(D3S1358 was defaulted as you mentionned but using any value for D3S1358, Ramses III always gets a probablity > 90% for sub-Saharan Africa.)

1) Sub-saharan individuals

African America:
Sub-Saharan Africa 99.2%
Eurasia 0.6%
Asia 0.3%

Uganda:
Sub-Saharan Africa 93%
Eurasia 4.3%
Asia 2.7%

2) Eurasian individuals

South Italian:
Eurasia 59.2%
Asia 28.8%
Sub-Saharan Africa 12%

Berber:
Eurasia 47.4%
Sub-Saharan Africa 37%
Asia 15.6%

Saudi Arabian:
Eurasia 45.6%
Sub-Saharan Africa 42.7%
Asia 11.6%

Scottish:
Eurasia 63.4%
Sub-Saharan Africa 31%
Asia 5.6%

Turkish:
Eurasia 62.6%
Sub-Saharan Africa 19.6%
Asia 17.8%

3) Asian individuals

Korean:
Asia 77%
Eurasia 18.6%
Sub-Saharan Africa 4.4%
