View Full Version : Y2395, PF6155 and Z280 - not peers anymore?

A few months ago I was tested with Big Y700 and it turned out that I belonged to one of the branches under Z284 (Y2395). I still don't have any match in the block tree. I still don't have any match at Y-111 or at Y-67 level. I just have one match (-1 genetic distance) at Y-37 level (that wasn't tested beyond this level and is unwilling to do so) and I have many matches at Y-12 level. I know that Y-12 matches are too general to draw any conclusion, however, I couldn't help to notice that all my Y-12 matches belong to either Z284 or Z280 branches and I don't have any match that belongs to PF6155 branch. The same rule applies to Y-500 (STR) matches, I have a few close ( 12-14 STR differences out of 400 STRs) from Z280 branch, especially from its Y33 sub-branch, however, still most of my matches belong to Z284 branch.

As far as I know, Y2395, PF6155 and Z280 are supposed to be peers. My conclusion is that Y2395 and Z280 are closer to each other than to PF6155. I suppose that, sooner or later new SNPs will be found that will make this division clearer.

What do you think?:)

Consider uploading your BAM file for BigY700 to www.yfull.com - a site for a secondary analysis of your Y-chromosome data. Ask others to do so. Yfull can have samples from other vendors as Veritas, BGI, Dante or FGC.

There is nothing more to conclude from these divisions as they all come from the common level of Z282 and even the highest coverage tests shown no recent changes in their mutal relation. PF6155 has more SNPs in the block and could have arisen later or sooner than both other SNPs but still Y2395, PF6155 and Z280 are absolutely independent when downstream from Z282.

You may get some matches after YFull starts an analysis of the Viking Era samples from throughout the Europe and you will upload your raw data here (.BAM file is considered but also .VCF from what I have heard)

Please correct me if I'm wrong but in the Y-12 panel are the slowest changing STRs, so how come I only have matches among Z280 and Z284, but don't have any match with PF6155 or its downstream M458? My point is that PF6155 may have divided earlier from the common ancestor of both Z280 and Z284, but current SNP coverage cannot demostrate it..or am I just a victim of convergence? :confused: :)

You are just a victim of convergence :). Most of my Y-STR matches belong to the specific Z284 subclade to the extent, that I was initially suspected to belong to Z284 (it turned out differently, obviously).
