    Question Disparate results with Ancestry/23andMe/FTDNA

    I started off with an Ancestry.com DNA test, then did 23andMe a bit later, then transfered my 23andMe to FTDNA. The results are quite disparate; thankfully I have a well-documented family tree with which to compare. I am mostly English and Scottish, perhaps less than a quarter German, and 1/8th Croatian.

    AncestryDNA:

    Great Britain 64%
    Ireland 8%
    Europe East 7%

    Low Confidence Region(s):

    Italy/Greece 6%
    Iberian Peninsula 5%
    Europe West 4%
    European Jewish 3%
    Scandinavia 2%
    West Asia 1%

    23andMe:

    Northwestern European 84.4%

    British & Irish 35.0%
    French & German 16.9%
    Scandinavian 1.7%
    Broadly Northwestern European 30.7%

    Eastern European 2.9%

    Southern European 2.3%
    Sardinian 0.4%
    Broadly Southern European 1.9%

    Broadly European 10.2%

    Ashkenazi 0.0%

    FTDNA:

    European 95%
    Jewish Diaspora 5%

    Scandinavia 44%
    Iberia 25%
    West and Central Europe 11%
    British Isles 10%
    East Europe 5%

    Of the 3, 23andMe is the most accurate. I can see how these tests would lump my German ancestry in with Great Britain, Scandinavia and Ashkenazi, but FTDNA's 44% Scandinavian and 25% Iberian - I have no Iberian ancestry - seems like wildly inaccurate algorithms to me. I don't think I'll be paying for their Y or MTDNA services unless someone can convince me these results are worthwhile. I just don't see it.

    I believe Y-DNA and mitochondrial DNA are what FTDNA does best.

    You're not the only one. If you have some time, read through some of this thread. Results were all over the place.

    But I agree with Randwulf that their Y and MTDNA services are the best right now.

    23andme is the most accurate autosomal test as far as I'm concerned. FtDNA does a good job for few people but many if not most get downright strange results

    Each calculator has a different timeframe they are looking to (23andme is roughly 500 years, Ftdna is roughly 2,000). This will cause results to differ a bit.

    23andme is 300 years; My Heritage is 500 years.

    FTDNA myOrigins is trash. A lot of people are missing an ethnicity that shows up at a high percentage in both parents and is also in the genealogical record. Since ethnicities can't skip generations the missing large percentage being swapped for another can't be explained away by a testing of a time period of 2,000 years as opposed to 300 years.

    Ethnicity calculators are very different from Y-DNA and mtDNA testing. FTDNA does a great job with those tests regardless of how abysmally bad of a job they do with myOrigins. Don't throw the baby out with the bathwater. Go with 23andme for the ethnicity calc and FTDNA for y
    Y-DNA and mtDNA testing.
