  • 60 No Calls on Y-STR values

    Just got my big Y test results back and confused by them. Was told that I was H-Z13997 group and could not find anything about this subgroup. Not sure which haplogroup forum to even join.
    What's even stranger is that there are "no calls" on 60+ of my Y-STR values. How is that possible for so many of them. My tests were delayed 5 times due to COVID and now it seems large portion of my Y-STR values are missing.

    Interesting. Only a couple examples on YFull. Indian?

    Note, you might have to hover over the field reading "+39 SNPs" in order to see that Z13997 is part of the block named Z13969.

      I had no idea it would be Indian.I'm most of African and European heritage but who know's what lurks around a family tree. I don't even know what haplogroup forum that I can join.
      Could find nothing about my subgroup its like its non-existent. Quite frustrating as not sure where to turn. But isn't it weird to have so many "no call's on Y-STR or is that normal?

        Maybe it's a newly discovered subclade. Sucks not to have any info. But then again maybe you could look at it like you're a pioneer? We know there are at least two other donors who are Z13997+. Maybe join YFull, too, and see if you can get in touch with them to do a project? If nothing else, you could work on estimating a TMRCA, to kind of put things in historical context.

        I bet the H project guys could help you.

        Maybe someone at the company can help on the STR issue. I don't have much idea myself.

          Y111 are the most important STR and you have calls on all of them.

          There is a reason why the name of Big Y is BigY-700. You get calls for at least 700 STRs or more ( including the 111). If you have a call on at least 700 STR, then it looks normal.

            Yes; that is a lot of missing STRs.

            I see on the FTDNA YTree that immediately upstream of H-Z13997 is the SNP H-APT
            H-APT is be dated to about 24,000 years ago on the Indian subcontinent.

            Downstream of H-APT are 4 clads:
            H-P194 ~800 years old
            H-P266 ~800 years old (Indonesia)
            H-P80 ~1100 years old, but with another SNP: H-B375 downstream.
            H-P13997 ~800 years old

            It is exceptional for their to be a such a long gap between 24,000 years to 800 years.
            Dating of SNP is difficult. STRs are better for dating, but with so many missing, there are limitations.
            So, the 800 - 1100 year age could be off significantly.

            Only 11 descendants of H-APT on SNP tracker site.
            I'm sure there are many more living relatives, but few have tested and uploaded their results.

              The very small number of recent nodes in the H haplotree, as mentioned by Andrew Ross, suggests to me that very few samples from this group have been analyzed with Big-Y or similar technology. But the fact of belonging in the H branch certainly adds a new twist to your genealogy. A personal mystery about your patrilineal ancestry that could lead you to some very interesting discoveries! Best of luck with your research!
