    Yseq tested me positive for CTS723. What next?

    Hi Yseq tested me positive for CTS723. But Yseq tested me negative for A12446 and Y26376. So I assume I belong to an unknown subclade of CTS723?
    What can I test next? Does it make sense to do a Big Y test?
    My main motivation is to know more about the Neolithic, Bronze Age etc history of my SNP and Haplogroup. Can anyone help?
    Thanks

    You said you already tested BigY,and you are CTS682,how can you be both CTS682 and CTS723?And if you already tested BigY,why should you test YSEQ,very strange

    Hando, there needs to be a lot of decent quality ancient DNA from Asia in order to know more about the Neolithic, Bronze Age etc history of your SNP and your haplogroup. If you get a BigY test it will only be to determine where you sit under the CTS723 branch. If you share novel SNPs with one of the two kits at YFull and you get a YFull analysis then you'll get a new branch and possibly a new TMRCA. If not then you will get a list of novel SNPs but you will still be in the CTS723 branch. If you are negative for a phylogenetic equivalent then you will beak up the current branch of CTS723 into two branches. It is up to you to determine if the above is are good enough reasons to get a BigY test.

    Hi Sahaliyan, actually I am CTS723 via YSeq. And the CTS682 is actually my cousin via Big Y. It is not me. Sorry for the confusion, but I did not want to have to explain that CTS682 was my cousin all the time I commented. I did not want to write a long explanation every time.

    Hi Armando, what exactly do you mean by the bolded sentence above? If I do not shares a novel SNP with one of the two kits on YFull I will split the current branch of CTS723 in two?

    Also are there already two kits at YFull for CTS723?

    Z24622, CTS2315, Z24621, 24625, Z24624 are phylogenetic equivalents to CTS723.

    If you are negative for any of the following SNPs - Z24622, CTS2315, Z24621, 24625, or Z24624 that means you are negative for one of the phylogenetic equivalents to CTS723.

    If you are negative for a phylogenetic equivalent to CTS723 then the branch for CTS723 will be broken up into two branches. One branch with the SNPs that you are positive for and another branch with the SNPs that you are negative for.

    Only if you are also negative for one of the phylogenetic equivalents to CTS723.

    There are four kits that are positive for CTS723 but two are negative for Y26376. They are kits NA18561 and YF06888. https://www.yfull.com/tree/O-CTS723/

    Thanks. Accrding to that link CTS723 is about 4,000 years old and since the two kits are from china it appears to have originated in china. Perhaps during the Bronze Age.
    How old is CTS682? And how old is CTS2272?

    No idea since they don't show up with a search with https://www.yfull.com/search-snp-in-tree/

    If you try some of the upstream SNPs you might get a hit with a search.
