We do two types of tests. One is like 23andme's "Advanced Global
Similarity", except that we do more "dimensions". For people with
ancestry outside Europe four of these are shown; for pure Europeans our
World graph is essentially identical to 23andme's so instead we show
our European graph, which includes (at lower right) the Adygei, a tribe
living on the eastern shores of the Black Sea. The higher dimensions do not
give additional information for pure Europeans so they are not shown.
You are shown as the large cross. Other testees may be shown as white diamonds.
You are between Orkney (purple) and Russia (Red). Russia means Moscow, which
is far to the east of where you said you come from, so your position
is as expected, between there and Orkney (Scotland).
We also do quantitative tests. These come in three flavors, first
without South Asia (represented by Pakistan) and the Mideast, second
with South Asia, and finally with all three, as comparison panels.
The typical random error in the data (standard deviation) is 1%, meaning
that numbers less than about 2% are not highly significant. There are also
systematic errors. In particular, there is cross-coupling of values for
Europe, the Mideast and S. Asia. For example, on the middle panel, a pure,
northwestern European measures about 9% S. Asian, and on the third panel
they typically measure 4.5% Mideastern and 8% S. Asian. Actual people from
South Asia or the Mideast always test at least 15% European.
For each test person, specific comments may be added below.
Europe 97.9%
Oceania -0.4%
America 2.2%
Africa -0.1%
E. Asia 0.2%
Europe 91.3%
S. Asia 9.7%
Oceania -0.9%
America 1.8%
Africa -0.6%
E. Asia -1.5%
Europe 88.8%
Mideast 3.5%
S. Asia 9.1%
Oceania -0.9%
America 1.9%
Africa -1.0%
E. Asia -1.5%
These also are perfectly as expected. Persons from northeast Europe
test lower on Mideast than do far western Europeans. They also,
for some unknown reason, test 1-2% American, even though there is no
close connection.
