    T-T2-T2i2 - James Lick

    Hey there guys..

    Took a Living Dna test about a year ago which gave me a generic Mtdna haplogroup categorization as T. Earlier this week were recommended to try the James Lick mtdna haplogroup analysis website which gave me this result

    Is this analysis trustworthy? Would the issue be in the Living Dna testing? What the imperfect match really means? Does it mean I don't fit in any of this haplogroups but actually in another one??

    I know there's deeper mtDna testing around but i'm not interested in taking it at the moment.


    Thanks!!

    It looks like the James Lick calculator is struggling because LivingDNA didn't test enough markers to get any detail beyond T.

    Before you spend money on more testing, what is your research goal regarding mtDNA?

    So there's nothing that makes me close to the T2 or T2i2 listed there?

    Well it's probably not T2i2, that appears to be Iranian.

    If you want detail like on this tree, buy FTDNA's full mtDNA test and then send the results to YFull --- https://www.yfull.com/mtree/T/

    Maybe someone else can help interpret this.

    Yeah.. I googled the mismatching markers to check if they fit anywhere else but couldn't find anything..

    James Lick's mthap is an excellent tool for mitochondrial DNA analysis. I would say it's entirely trustworthy given the right data. The issue is the lack of data from LivingDNA. LivingDNA only tests 4700 mt SNPs out of the 16569 locations on mtDNA, so that's only 28%. Furthermore, LivingDNA's raw data only reports the results for SNPs where you score a positive result on their test - it doesn't list the SNPs that you're negative for or a no call for. This is important data for a haplogroup predictor.

    Any predictor is only as good as the data input. To use a hypothetical analogy, if I tell a friend to meet me halfway around the world, write out a detailed five page itinery that will definitely get him there, but I tear all the pages up into pieces and only give him a small portion of the torn up scraps, he might get there or he might not. If he doesn't, it's not because his map reading skills are untrustworthy, it's because he didn't have enough data to make the right decisions.

    So even the living dna's T result might be wrong?
