    I tested it with a few samples with elevated Amazigh ancestry, it seems not too bad

    Hello
    I did the same for Portugal, but I removed Jewish and Corsica as there was too much overlaping.Portugal Admixture.JPG

    the main difficulties is to avoid overlaping between the 3 populations: Levantines, Sephardic Jews and Arabians.

    Amazigh: OK -> as you are the average of your dad and mom
    Arabian: NOK -> overlapping with Sephardic Jew and Levantine
    Sephardic Jew: NOK -> overlapping with Arabian and Levantine
    Levantine : NOK -> overlapping with Arabian and Sephardic
    Sardinian: OK
    West_European: Globally OK
    I have never scored just the average between my mother and my father, neither in simple models I have ocasionally scored less NA than my mother, what´s is quite strange (but not impossible, of course).

    My father can score sometimes more in Arab than NA, and being Andalusian quite low.

    But you know, all depends on references and how they work together.

    Edit:correct text.

    One of the groups includes populations that are very different from one other (West Euro), and since this is the most significant group used in the model it leads to imbalanced and unstable outputs.

    If two people from the same region benefit the most from two different sources, for example one from Basques and the other from Provence, the output will forcibly be distinct between them because Basques have virtually no post-roman ancestry which is not the case for Provençals, consequently this will skew the rest of the output, the one who benefits from Basque will probably get a lot more Sephardic, since it's the closest reference to our Mediterranean ancestry. Sardinian also varies a lot but because of different levels of steppe ancestry within the main source.

    We already know that a model for Iberians based on European references from a non-Iberian country and with Basques as solely Iberian reference, is going to give us a fairly high score in non-European populations, but I don't want to think about any bad intention of the one who posted the model, and I prefer to think that what they want it is not to discriminate well that non-European contribution present in Iberians in its percentage, if not rather in the proportion of different origins of that input.

    But I understand perfectly what you mean, and it was my first thought when I see the references used in the model.

    But since this is supposed to be a serious forum, away from identity agendas, I prefer to think well.
