  • SNP test for Deep Sub-clades vs 12 to 37

    I have just received my (12-marker) y-results and was offered the upgrade to the deep subclade test. Will that test also give me the values for the other 25 markers commonly discussed or is that still another seperate test? What is the relative merit if they are different? It seems to me if I received, for example, a refined classification to R1B1c7 but had no additional information on the other 25 markers I would be no further along in comparing notes with others... if anyone can clarify, thanks!

    I also received the mtDNA test results last week. This identifies my haplogroup as W but notes that the pattern matches some L3* as well. Does this mean that FTDNA only surmises W based on the pattern they can see in HVR1, but there are some L3* as well with the same deviations from CRS? Or is the classification as W definite based on tests done outside of HVR1?

    Sorry if these are FAQ's, but I've checked all over the FTDNA site and done various Google searches and couldn't get answers to the above...

    Welcome, pausanias!

    Those are good questions. I am wondering about them, too, since I am considering a deep clade test.

    Are you R1b? Please join the tribe on the IF YOU ARE ONE, BE ONE thread and discuss this stuff with us. There are some knowledgable people over there.

      These are really two different sets of tests that can be complementary.

      Deep subclade testing is testing your SNP markers.

      Y-DNA 12, 25,37 and 59 are STR marker tests.


      So the deep subclade test is not really useful from a genealogical perspective because R1B1c7 is thousands of years old (vicinity of 5 to 10K years). Whereas STR are more volatile and hence useful for genealogy (can change in a few hundred years or even just in one generation).

      So if you are trying to establish genealogical ties, upgrade your Y-dna to a 25 or 37 marker test and find other distant branches to test. If you have no close matches or have matches that are ambiguous 22 out of 25 for example. You could get tested for deep subclades as a way to rule out a relationship.

        mtDNA haplogroups are confirmed, not just predicted:

        In 2005 we began running haplogroup tests on every sample. The haplogroup test is now part of every mtDNA test we run. Currently we run a panel of 20 different SNP's on every mtDNA sample to attain the precise haplogroup of every mtDNA test we perform.

          Thanks a lot for the quick, useful, and informative responses. I will definitely be participating in the R1B1 thread/forum.
