Anyone who feels Russians are Mongoloid or significantly Mongoloid is as blind as a bat or biased. A small amount of admixture within a population tends to show itself in not so subtle ways.
This is controversial. According to ABD, people who show physiognomic characteristics of a race " generally have at least 30-35% identity within that group." This statement is not on the ABD web site; it was provided to me with my test result. This doesn't accord with some of the testimonials posted at the Kerchner DNA log I linked above. There are people who claim they have morphological features of one group, e.g. epicanthic eye folds and dental shovelling, but their test results show well under the 30-35% general morphological minimum for that group.
Again, my most likely estimate of East Asian genes is 2%. This is within the test's standard error range of 2-3%. The confidence range that I got for this group is 0-12% at two-times-less likelihood. While this result may be erroneous, it also may mean something. This depends on how my other family members test and how people test in a microgeographic area around my family's native Greek villages. I don't have genealogical records of my family tree, only vague oral accounts that do not go back more than a few generations. My ancestors were poor Greek villagers who didn't have the resources or concern to trace family history. Without a genealogical record or DNA test results of other family members, there's not much I can say about my result with more confidence. A microgeographic genetic study may reveal more or less about a larger group, such as an ethnic group, and even Cavalli-Sforza admits that more testing has to be done at the microgeographic level to better determine population genetics.
With Greeks I seriously doubt that a bunch of microgeographic studies would reveal much East Asian DNA; hovever, one or more areas may show traces of this DNA, whether it's old in the genome or was brought by more recent invasions/migrations.
