National Geographics Geno 2.0 Update.

The National Geographic's Genographic 2.0 Project is providing valuable information regarding our J-L24(M530) clade. I recommend taking the Geno 2.0 test over Family Tree DNA's (FTDNA's) Deep Clade test. Geno 2.0 will provide your current terminal branch of the Y-DNA tree, just as Family Tree DNA's Deep Clade test, however Geno 2.0, testing over 12000 Y-SNPs, may reveal, in addition, previously unknown branches.

I'm posting above the current J-L24 Y-DNA phylogenetic tree. It is quite different than the one I posted in December 2012! Just click anywhere on the chart for the full view. The chart was provided by Ludmila Ryabchenko, sponsor of FTDNA kit 171488 (Nickolay Ryabchenko). A clearer view of the chart can be found HERE.

What is new is the two large J-L25 branches(clades) defined by SNPs PF4888/PF5401 and F3133. They parallel our other major, in fact largest, J-L25 branch defined by the Z387 SNP (encompassing our DYS445=6 haplotypes). We suspect that most all members, subclusters, and subclades of J-L25(J2a4h2) will fall under the PF4888/PF5401, F3133, and Z387 branches of J-L25. This is a big step forward in our understanding of the J-L25 genetic tree. Currently, as seen in the J-L24 phylogenetic tree, PF4888/PF5401 unites the L243 clade with a new clade called PF5366/PF5368. In turn PF5366/PF5368 unites my own L229/L230/L264 clade with the L254/F659 clade. The L254/F659 clade also unites two other clades called M365.2 and CTS1489. Clearly we need additional testing of the PF4888/PF5401 clade in order to learn more about its genetic structure. We need at least one member of each of the L243 clusters (L243-alpha through L243-eta) to test (Geno 2.0 preferably with the possibility of finding new SNPs, but in the future FTDNA will offer individual SNPs for testing too). The L243 clusters can be seen in our FTDNA J-L24-Y-DNA Project Y-DNA Results section. The L243 clusters are numbered 02111 through 02117 (forest(dark) green clusters). We also need the many members of the L254 clade to test so that we can see how many are derived for the new F659 and CTS1489 SNPs.

A characteristic of the PF4888/PF5401 clade, first noted by David Dugas, is YCAII=19-23. It appears, so far, that all members of PF4888/PF5401 have YCAII=19-23.  This stands out from the ancestral state which is YCAII=19-22 found both in the F3133 and Z387 clades. This doesn't mean the PF4888/PF5401 clade is younger than the F3133 and Z387 clades. It just means that YCAII=19-23 happened early when PF4888/PF5401 was founded, while it did not happen in F3133 or Z387. In any event one can scroll through the J-L24-Y-DNA Projects Y-DNA Results section, observe YCAII, and see who might be PF4888/PF5401 via YCAII=19-23. One sees that the Cohen cluster (0214) and the Saudi-alpha cluster (0215) are likely also PF4888/PF5401 (but not tested yet). It would be good to see several members of the Cohen (0214) cluster take the Geno 2.0 test, hopefully we will find a SNP for this Jewish cluster that is L254-. The PF4888/PF5401 clade appears to have a European flavor and a significant Jewish component, but with lighter links to Lebanon and the Middle East. This may just be due to a lack of sufficient genetic testing from the area of the Levant (Lebanon, Syria, Jordan, Palestine, Israel, Cyprus, and Southern Turkey). Kamel Al Gazzah indicated that PF4888/PF5401 has an Ashkenazi component while F3133 a Sephardi component. However, interestingly, we observe that the Z387 clade has both Ashkenazi and Sephardi components.

F3133 appears to have more of a Middle Eastern flavor and a lighter European component. We will see how this pans out as more and more of our members test with Geno 2.0 or through FTDNA. Currently we have found that J-L192.2 shares F3133 with a new clade called F761. F761 currently includes the Ducas (L231) and Ward (L317) clades. Looking at YCAII=19-22 it appears that the Mughal-Timurid, Curtin, Al-Ahsaa, Najd, and Syrian-Anatolian clusters may also be F3133 and possibly F761. Again, it would be most helpful if at least one member of each of these clusters would take the Geno 2.0 test.

I'm looking forward to more Geno 2.0 results in the near future!
