    Population Admixture Map of Europe

    These are maps created by Eupedia.com using autosomal data from Dodecad K=12 population which measures admixtures of components such as Northwest European (West European), East European, Mediterranean, West and Southwest Asian as well as African in various populations.

    It is similar to the population chart given here: http://dodecad.blogspot.com/2011/06/dodecad-v2.html and the Dodecad v3 K=12 spreadsheet (https://docs.google.com/spreadsheet/...COCa89AJ#gid=0), however these maps show variance and give off a range based on averages, rather than the single average, since I'm guessing that almost all people of a given population such as North European, CEU, or German don't match the components given by Dodecad exactly but rather within proximity.

    Germany averages 52.7% West Euro according to Dodecad, and looking at this map, the 50-60 range encompasses most of Germany. However (although it may be wrong it's hard to tell exactly) the south and eastern parts of the country according to this map seem to see lower percentages 40-50, as you get closer to the alps, .and percentages over 60% in the far north. That the region occupied by current Germany encompasses several ranges of West Euro, as well as East Euro and Med suggests a genetic overlap encompassing a transitional crossroads between Northwestern, Eastern, and to a lesser extent Southern Europe, which is also reinforced by its subracial diversity.


    West Asian admixture distribution


    5-10% of West Asia is a typical score for most continental Europeans, with even lower percentages in Scandinavia, however a good portion of the 10-15% cluster seems to extend well above Italy suggesting the 10-15% range also isn't uncommmon for the southernmost Alpine regions.



    Southwest Asian admixture distribution

    The 1-2.5% range seems to be consistent among the Germanic populations in this map, I'm guessing it's towards the low end the further north you go such as Norway and Sweden, and closer to the high end further south. It is also interesting how the light green area is cutoff at approximately the Germany-Poland border, with much of Poland and the Northeast Europe being <1%.

    Anything above 2.5% may suggest Southern European admixture, since we don't see the 2.5-5% cluster until you get to central Italy.


    African admixture distribution


    The combined East African, Northwest African, Neo African, and Palaeo African admixture distribution of Germanics and most of Europe is generally less than 1%, so higher numbers may indicate Southern European ancestry.


    Comparing all these maps, I can envision a spot in Austria, East Switzerland or even Southern Germany where my mother would fit nicely based on her component admixture percentages from Dodecad. It's hard to tell exactly but I think it might be in Austria, East Switzerland, or even southern Germany. These maps would be nice if they had border lines as well.


    It's also interesting how that "eye" in Russia in the right hand corner appears in nearly every map, having lower West Euro and Med, but higher West and Southwest Asian than the area surrounding it. That area might encompass a distinct population.

    The Volga Germans.


    Also, the area along the Caspian Sea that is gray in most maps is inhabited by the Kalmyks, Mongols who moved there in the early 1600s.

    These are averages. Some countries contain more admixed levels, but it is not even across the board.

    For example:

    If I was a 1/8 African, that self-identified as a Ethnic German, or British, Dutch, Or 1/4 Indonesian, it would all be averaged.

    We have people in every country this day and age that are of pure or impure stock.

    We need to be vigilant wherever we are.

    Just because some countries may have had more colonialization, or liberal immigrant policies does not mean that the Germanics there are any less Germanic.

    This means that some people claiming to be ethnic whatever, are of impure bloodlines.

    That is why I do not like averages, as it lumps everyone together.

    Also remember that this represents ancient gene flow so is useful for the study of human migration patterns. For example the West Asian and SW Asian percentages are good for showing the flow of the farmers out of Anatolia or the migration of R1b.
