    Suggestions for improving Ethnicity Estimates on AncestryDNA

    Hopefully ensuring that Ancestry's update will be a step forward and not a step backwards Some of the suggestions below are specific for improving the African breakdown on AncestryDNA. However most of them are valid across the board.

    Feel free to discuss & add your own personal wishlist!


    1. Bring back the continental breakdown display (subtotals specified for each continent)
    2. Mention the “aggregate ethnicity estimates” for each migration/genetic community (used to be available in the beta version)
    3. Enable the Ethnicity Estimate Comparison feature for all customers and not just USA-based smartphone users.
    4. Show ethnicity/admixture of shared DNA segments with your matches (chromosome browser).
    5. Avoid misleading labeling of ancestral regions. Providing a false sense of accuracy.
    6. Maintain current coherency of African breakdown and improve by creating less overlapping and more predictive regions
    7. Add more historically relevant African samples to Ancestry’s Reference Panel. In particular from Angola, Burkina Faso, Guinea Bissau/Conakry, Liberia, Madagascar, Mozambique and Sierra Leone.
    8. Create new regions and/or migrations centered around these historically relevant samples.
    9. Create new African “migrations”, a.k.a. genetic communities. In particular for Nigeria & Ghana, as sufficient customer samples may already exist.

    I don't trust ancestryDNA because it is American company and sorry but Americans are anti-intellectual anti-scientific idiots. See the book "The Age of American Unreason" by Susan Jacoby. I trust the raw data but not their analysis.

    Are saying that all science performed in America is garbage because all Americans are dumb? Isn't your nationality listed as American?

    The PhDs working on the ethnicity estimates are hardly "anti-intellectual anti-scientific idiots" just because they are in America (which, by the way, is home to all sorts of cutting-edge science and internationally renowned academic institutions).

    I live in Northwestern Europe and I can also do EE comparisons with my matches on my iPhone.
    Mc Donald:
    Most likely fit is 62.4% (+- 9.5%) Europe (various subcontinents)
    and 37.6% (+- 9.5%) Mideast (various subcontinents)
    Dodecad World9:
    1 50% S_Italian_Sicilian +50% Dutch @ 1.083
    2 50% German +50% S_Italian @ 1.126
    3 50% Dutch +50% S_Italian @ 1.148

    That's good to know! When I tried downloading the app it gave me an error because it was restricted to the US. Perhaps they have adjusted this in the meanwhile. Either way I would also like to use this very useful feature on my PC, as i perform most of my research from my desktop pc.
