We have two more Big Y results for branch Z280. This includes a member of the "Old Carpathian"clade YP340 (more specifically YP372*) and a new member of the paragroup YP314* under S18681.

As suggested by the recent Big Y result for kit 152908 from clade YP569 under Z92, it seems that YP682 is positioned downstream of both YP683 and YP684, although the negative YP682 status of kit 152908 needs to be confirmed by the analysis of his raw data.

Two Big Y results have been added to my draft tree: kit 271891 from subclade YP269 and kit B7738 from subclade P278.2.

BigY-based tree for Z280 - 24.jpg


Here is a list of all 11 SNPs from the P278.2 level that are tested by Big Y:

2805051 G>A (M12427)
7010646 C>T (M12431)
7761370 G>A (M12436)
8467053 G>A (P278.2) listed among "known SNPs"
8610929 C>T (M12439)
14042511 A>G (M12443)
14813138 G>C (M12446)
19382613 G>A (CTS10301) listed among "known SNPs"
19735420 T>G
21311350 G>A (M12456)
24006612 G>T

There is actually one more SNP that seems to be shared by both BigY-tested P278.2 members but it is located in an unstable region and seems to give unreliable (heterozygous) results in some cases.

26181642 A>T

The exact position of M12461 (22548435 G>A) on the above tree needs to be examined, as it is possible that this SNP wasn't tested in kit B7738 (thus likely representing a false negative for an SNP marker on the P278.2 level).

The most recent Big Y result for branch Z280 suggests that all previously tested S18681 members belong to a major subclade of S18681 that is defined by four or five SNPs downstream of S18681 and upstream of YP314. These SNPs are YP315, YP318, YP320, YP325 and YP448(?), but all this needs yet to be verified by analysing the Big Y raw data for kit 2546 who seems to be negative for these five SNPs while showing 15 private SNPs downstream of S18681. I will update my draft tree as soon as these suspicions are confirmed.

As reported by the owner of kit 2546 who analysed his raw data files, he is indeed negative for five SNPs upstream of YP314 and downstream from S18681.

We have two more Big Y results for R1a-Z280: kit 229574 from cluster CTS1211-B3 and kit 246277 from a newly discovered subclade YP940 (under YP389 in clade L365). The YP940 level under YP389 includes two SNPs upstream of F2686.2, namely YP940 (7556896 G>C) and YP941 (17877935 T>C ), both shared by kits N50210 (F2686+) and 246277 (F2686-).

So far, we have received the Big Y results for three separate clusters within the hypothetical CTS1211-B grouping that includes six distantly related clusters B1-B6. All these clusters are confirmed as negative for CTS3402 (and either confirmed or presumed as negative for YP340, another major subclade of CTS1211). Based on the most recent Big Y results, it seems that B1 (a cluster predicted to encompass B1A and L784(B1B)), B2 and B3 do not share any BigY-tested SNPs downstream of CTS1211, which is a bit surprising (at least for myself), as I have considered it very likely that most (or all) clusters from the CTS1211-B group are somehow related not only to each other but also to all members of another subclade CTS3402 with whom they share a relatively rare result DYS464a=13. In other words, it seems very unlikely that the mutation 12>13(>14) at DYS464a was an independent innovation in each of those seven groupings under CTS1211 (i.e. in CTS3402 and in clusters B1-B6), as this STR result is very rare (or practically absent) in all remaining subclades of Z280, including YP340, S24902 and Z92.

It should be noted that two out of six SNPs from the CTS3402 level are not covered by Big Y. These are Y2192 (6622559 G>T) and Y2193 (13958937 T>C). Thus, there is still a chance that one of them may define a potential subclade of CYS1211 that encompasses both CTS3402 and at least a significant portion of CTS1211-B. Also, it is still possible that there is an SNP marker that is not covered by Big Y but is shared by most members of CTS1211-B while being absent in CTS3402. To verify both these presumptions, we would need at least one or two members of CTS1211-B (preferably from different subclusters) to order the Y Elite test offered by FGC. Alternatively, it would be useful to order Y2192 and Y2193 from YSEQ by at least some members of CTS1211-B, although in such case we would test only one of the above hypotheses (i.e. that with CTS3402 and CTS1211-B sharing a common SNP marker under CTS1211).

FGC also offered Y-Prime. This is much smaller range, but it is much cheaper!
Does it work?

I have included 12 new Big Y results into my draft tree. Together, we have 77 Big Y results for branch Z280 and when including three additional BigY-tested Russians from the Y2902 subclade who haven't joined our R1a FTDNA project, this number grows to 80.

With so many Big Y results coming for Z280, I will probably need to create separate trees for some major subclades of Z280, just to maintain a proper resolution of the images.

BTW, those three BigY-tested members of branch Z280 who haven't joined our project are from the paragroups Y2902* (kit 55450, surname Klyosov) and Y2910* (kits 279307 and 220740, surnames Ageev and Shabanov, respectively).

Michał,

I congratulate! Excellent result!
