Link to I-L621 tree showing major STR clusters (Updated)

Click here to see our latest draft tree for I-L621.  We have used colors to show STR marker clusters. For example, the branches belonging to Dinaric-South cluster (DYS448=19, DYS449=30 or similar, and DYS565=9) are colored blue.

We also show the many Dinaric-North branches, the Disles branches, and two small clusters within Dinaic-North: a Jewish cluster, and a Mediterranean cluster. All of these clusters can be easily identified by STR marker values.

This colorized tree is not attempting to show a geographic or ethnic/historical origin for every branch. We are only showing STR clusters. For example, there are no known STR marker values specific to the I-Y4460 branch, therefore I-Y4460 is shown as part of the bigger Dinaric-North STR cluster.

UPDATE 29 August 2016--You will notice that the tree shows that the Dinaric-South group belongs to the I-PH908 branch. PH908 is a SNP that was first reported in the Pille Hallast survey in 2014. This SNP is not covered by the Big Y test and most those who have Big Y test result have no call status for PH908. Some have one or two positive or negative reads. Two persons from DinS cluster (I-S17250* and I-Z16983 haplogroups) have positive T+ results in their YFull reports. Three persons  who have S17250+ and BY128+ results have negative C- results. Two persons from I-Y4460 and I-Z17855 haplogroups also have negative results. The position of this SNP relative to Y4882 is to be investigated.  PH908 could be a characteristic SNP for the Dinaric South cluster. The PH908 test is available at and we recommend it for all Dinaric-South men. Two Din-S men have already reported PH908+ results from YSeq.

  1. Great :)

    Thank you for all your collective work in such a great colored representation. I realize notes which u mentioned in post, but still, such visualization really helps me for better understanding clusters and cross/neighbor-clusters relations/positions.

    Top question for me so far - when FTDNA will have ability to test one of these: A6105, A6106, Y16810, one of which I may be positive, because rest of parallel branches I am already negative.

  2. btw, since previous version, on this we also still have note "and two more novel variants" near by mentioned by me above. I realize it might be not ready to show all info, but what else info is out there?
    Is this about YF04010UKR [UA-05] and YF02238LVA [LV-RIX] from yfull?

  3. Zdenko and I don't know very much about FTDNA's plans about new SNPs. In general the newest SNPs are not available as individual tests at FTDNA, only as part of the I2-P37 SNP pack. A6106 is included in the FTDNA SNP pack and A6105 and A6106 can also be ordered as an individual SNPs from

    I expect that eventually FTDNA will update the SNPs in the I2-P37 SNP pack or create another SNP pack specific to I-L621 for example.

    There are "two more novel variants" equivalent to A6105, A6106, Y16810:
    13682157 G to A
    22669350 C to T

    Probably the reason Zdenko didn't list these on the tree is a lack of space. But these SNPs are not listed at the YFull tree, so maybe there is some additional reason.

  4. Yes, the I-A6105 on Zdenko's draft tree is the same as the I-Y16810 branch on the YFull tree. The YFull tree includes only people who have ordered the service which costs an additional $49, and the YFull tree identifies samples only by a YF code, and also a country of origin like UA-05 and LV-RIX. Zdenko's trees identify samples by a FTDNA kit number, and usually Zdenko's trees include more samples and more branches because not everyone who has done a Big Y has sent their data to YFull.
