J2a-L26* SNP found: Z6064? New seldom clade J2a-PH890

First the FTDNA deep clade and then even Geno 2.0 left a considerable part of J2a-L26 kits without downstream haplogroup. In 2013 Y-sequence results first showed that PF5088 unites L24 and M67 together with many other clades substream of L26 and as parallel group J2a-M68 samples from 1000 Genomes Project and Sardinian samples 848-849 (Francalacci et al 2013) allowed the […]


Three J2 found at Merovingian buriel site (Roman-Frankish transitional period)

Thanks to the find of Irakli Akhvlediani with post to the J2 Fb group and the translation of Robert Sanders we gathered this fascinating information. Het Merovingisch grafveld, in: R.C.G.M. Lauwerier & J.W. De Kort 2014: Merovingers in een villa 2. Romeinse villa en Merovingisch grafveld Borgharen – Pasestraat. Onderzoek 2012.

J2a-Z6049: finally more substructure in this old J2a* clade

I worked trough the evidence for this old J2a clade for ISOGG certification and found new structure: http://tree.j2-m172.info/?Hg=J2a1b Z6049 is equivalent to S18476/SK2198. A new subclade is SK1312 for whom so far all Georgian BigY are positive: 270352, 259005, 258936 Since Z6048 has no coverage in BigY we have to wait until FTDNA is able to complete the BigY of […]


Ancient Y-DNA discussion: no J2a in pre-Bronze Europe?

UPDATE 10 November 2014: The publication of DNA data from Neolithic to Iron Age Hungary did make a revision of this article necessary, as the sample BR2 (ca. 3,200 years old) was found to be positive for J2a-M67-CTS3261 (Kandell T.). His autosomal analysis lets suspect that he descends mainly from Western ancestors with no near connections to Anatolia Caucasus or […]

Minimal reference J2 phylogeny

The makers of the mtDNA reference phylogeny (Mannis van Oven, et al.) did setup a “minimal reference” for the Y-DNA haplogroups. Team members are in contact with Mannis to achieve an updated and optimized J2-M172 minimal  reference: . Primary goals of www.phylotree.org/Y/: […] optimal  global  discrimination capacity  based  on  a  strongly  reduced  set  that  includes  only  the  most  resolving  Y-SNPs. […]


J2 phylogeny in 1000 Genomes Project

Under the lead of Greg Magoon a group of citizen scientists (including J2-M172 team members Bonnie Schrack and Chris Rottensteiner) were involved in the analysis of a high-resolution a priori maximum parsimony Y-chromosome (“chrY”) phylogeny created from data of 1292 male samples in the 1000 Genomes Project. 63 of those samples are in haplogroup J2-M172 (42 in J2a and 21 […]


J/J2 fusion under way @ FTDNA 1

J2-Project admin Angela Cone who has blogged in Nov. 2012 about the reasons of low activity since 2008: “Sir Nico, Earthquakes, and Hypodopaminergia” and already announced her wish to have of team of  co-admins, everyone dedicated to a speciality area. “Before this new J2 project incarnation can fully emerge, there will be a period of metamorphosis over the next few months.  Behind […]
