  • About the latest “My Origins Version 3”


    Lately I have checked the updated results for my V3 Origins and they are as follow:

    West Central Asia: Indus Valley 97%
    Middle East Jewish: Mizrahi Jewish <2%
    Arabian Peninsula <1%
    Anatolia, Armenia, & Mesopotamia <1%
    My V2 old results were as follow:

    Central/South Asian 55%
    Asia Minor 45%
    I wonder on what genetic bases these percentage have been calculated?!

    It’s seemed to me they gave me the highest percentage because I have given them my latest ancestor’s location!!

    Is the new "My Origins Version 3" cluster zones represent a realistic genetic map distribution??

    Finally, Why I’m getting a trace of a “Jewish Diaspora” even it’s very low?!! (With all my respect to those people cultural heritage)

    Can anyone explain in a scientific logical sense about these calculations!

    FTDNA has not yet put out information about the reference populations used for myOrigins 3.0, such as in a white paper. The reference populations are used to determine to which populations clusters each customer is closest. FTDNA, as far as we've been told, does not use information provided by individual testers to come up with the population clusters and percentages for that tester. On the FTDNA Learning Center page "Does the myOrigins tool use non-autosomal DNA results?" it says:
    Only your autosomal DNA results from the Family Finder microarray chip are used.
    While this statement is addressing other forms of DNA (mtDNA, X chromosome, or Y-DNA), I would also take it as some evidence that ONLY your autosomal DNA results are used to compare to reference populations. Your forum profile shows you are from Gedrosia, so your result of 97% for "West Central Asia: Indus Valley" sounds pretty accurate, unless I'm wrong about the location. I would disregard the trace amounts. If you look at your myOrigins 3.0 results, and hover over the small "i" in a black circle shown with your trace amounts, it shows this message:
    A trace percentage indicates a very small amount of shared DNA in common with the corresponding population. Smaller DNA segments are more likely to be misattributed.
    So, consider that these trace amounts in your estimate may be misattributed. There are similarities between different populations which can be misidentified (misattributed) as one or the other. Among others, some people with Mediterranean and Middle Eastern ancestry sometimes show a misattributed percentage of Jewish in their results. Also consider that myOrigins may reflect ancestry beyond what we can find out about our own in the last few hundred years: the page "How many generations in the past do myOrigins results reflect?" in the Learning Center says:
    myOrigins results are your personal genetic ancestry that reflects the last 100 to 2,000 years (about four to 80 generations). They may also reflect one population that mixed with another in ancient times and became fixed in one of your populations.
    We all need to keep in mind that ALL ethnicity estimates, from ALL the companies, are still their most accurate only at the continental level; once beyond that, interpretations may be off. And ethnicity estimates ARE NOT the most accurate part of DNA testing for genealogy. Rather, the closeness of your matches and where they match you on the chromosomes ARE the most accurate. The ancestry of your matches will reflect your known ancestry better than the ethnicity estimates.

      Thanks for your valuable inputs & feedback

      You are correct I have mentioned on my profile I’m from “Gedrosia”, But it’s a broad region, most ancient maps as far as I’m aware may put the Indus river at the end border to the east. From the DNA region perspective, it’s a totally different environment region.

      As for my ancestor generations records, they lived in the west region of “Gedrosia” which is also a different DNA climate trigger. The Gedrosian “Makran” cluster populations in this region have their own unique DNA frequency range which could identified them separately from Indus river, any people migrated to this region (i.e Central Makran Range) and live in it for enough long time (over many generations) their “Autosomal DNA” will be triggered to be altered uniquely by the environment adaption no matter their “Haplogroup” belong.

      I’m not arguing that I may have some percentage portion of a DNA from Indus river populations which will increase as we get closer to the region and fade if we go far away, but they give me 97% which indicate I have almost like a pure royal Indus river blood!! C’mon FTDNA, be more a reasonable sense in term of the cumulative genetics references & do a little precise research about this region.

      I totally agree what have you said
      “Among others, some people with Mediterranean and Middle Eastern ancestry sometimes show a misattributed percentage of Jewish in their results…”

      It seems to me that FTDNA giving a free trace bonus for everyone from the surrounding regions that may subjected to the Jewish migration, because my son results also included these traces for Mizrahi Jewish <1% and also Yemenite Jewish <1%.

      My main observation about this matter that FTDNA relate A heritage cultural ethnics to the genetic physical factors which is solely a region based.
      I think most of us agree that the cultural based ethnics such as religion, languages, nationalism…etc are a gainable society values and they are not inherited through DNA genes over generations.

        Thank you for telling us about you family seeing this phenomenon of false estimates in the Jewish categories, Dr.SYSTEM. It is well-established that Mizrahi Jewish and nearby non-Jewish populations didn't mingle during the autosomal timeframe and were basically genetically isolated from each other since the 7th century at the latest.

        Unfortunately, some Middle Eastern people from non-Jewish families trust the fleeting glimpses of possible Jewish ancestry from the small percentages in the Mizrahi Jewish and/or Sephardic Jewish and/or Yemenite Jewish and/or Ashkenazic Jewish categories that show up in MyOrigins or MyHeritage or 23andMe and then when they find distant identical-by-chance matches who are Jewish who supposedly match them on small segments, they think they've proven it exists in their heritage. In populations that test infrequently, the proportion of false matches is higher than for someone who comes from a well-tested population. False matches are those that fail to pass rigorous phasing and triangulation tests inside GEDmatch. The segments often are only 6, 7, or 8 cM in length and the total percentages of DNA shared are usually under 0.2%.
