    The 1% Nigerian DNA of European people

    The number and ethnicities mentioned are examples of what I saw looking at many MH results on YouTube.

    MH rightly puts such cases in the low confidence category, but is it enough ?

    1. If such patterns exist on a regular basis, this is likely a systematic error that MH ought to solve.
    2. Due to the potential psychological effect, wouldn't it be preferable to put such cases in an "Conflicting" or "Unknow" category ?

    OOA admix at the very most.

    There has been no widespread mixing between Africans and Europeans up until the last century. Note that I'm not talking about white Americans here, many of whom have minor SSA admix.

    I had no idea MH had a low confidence category, but it's still shoddy especially when so many people take their results at face value.

    I would definitely consider myself Nigerian personally if it said 1%. Nigerian on my results.

    It's most likely something wrong with the algorithm as more sophisticated methods of inferring ancestry never indicate this sort of admixture in European populations (outside of those with North African related admixture, as this may transmit minor Sub-Saharan).

    I thought they corrected for this and it was no longer showing up for people?

    my wife shows 1% Nigerian. She's Iranian. My mom shows 1% Central American, which is doubtful. I show 1% Ashkenazi across all kits uploaded to MH including their own swab. Its likely some weird noise thing. Looking forward to their updated results they say they are releasing later this year.

    I still have 1.1% Nigerian. It's never changed since the problem first started.

    The only way that my family lost the 1% Nigerian was to delete my kits and re-upload. The estimate was the exact same except Nigerian was gone. I'm not sure if uploads to MyHeritage still get free access to everything though so I might not chance it now just to lose 1% Nigerian in the ethnicity estimate.

    I have not checked the dates of the videos. Hopefully, they did so.

    I did this 4-5 times back when it was free as an experiment, and unfortunately it didn't go away. Now that it costs to unlock the ethnicity estimate I'm happy to leave it how it is.
