Recent new NextGenSequence results being derived/positive for J2a-Z6048 (old J2a* and without considerable Caucasus presence like the brother SK1321/Y12622) allowed a substantial improvement of the phylogeny. See also tree.j2-m172.info/?Hg=J2a1b1, yfull.com/tree/J-Z6050/
Wim Penninx helped by filtering reliable combBED area SNPs from the two Punjab samples.
The YFull raw-data analysis of the Sardinian samples is the only way to reconstruct satisfyingly reliable terminal haplogroups out of this low-coverage-sequencing. In doubt now more samples are left in the same terminal group because too often assumptions without the possibility to check for underived/negative status revealed as inaccurate especially if based only on a few haplogroup defining SNPs.
Careful reanalysis of the ancient I0708 NW.Anatolia sample allowed to assess that Z6050, Z6052 are underived and therefore the ancient paragroup to date has no modern samples.
During the research Z43501, Z43503, Z43504 +65 were registered as defining the Jewish Z6048 group. Currently it is likely the two samples do not represent all of the Y-DNA diversity of the STR-cluster, so further testing will be needed. Trough ERR1395578 Jordan the YFull analysis possibly improved the tree (Z38481, S15572 and S23560/Z29422) and finally Z43567, Z43568, Z43569 +39 were registered to represent the two Punjab samples (one a new BigY result).
