46 Pre-Chalcolithic J-M172 main sub-haplogroups

With the goal to simplify the grouping and assignation an analysis of the YFull YTree v9.03.00 J2 Scientific View was done in August 2021. See for comparison Basic Tree Subclades of 2015 and FamilyTreeDNA Y-DNA Haplotree and Time Tree @ Discover FTDNA. Criteria: Resulting 46 J-M172 Sub-Haplogroups are linked, older ancestor groups mentioned for hierarchical reasons. If FamilyTreeDNA Y-DNA Haplotree uses […]


J2-M172@FTDNA Project Administration Changes Announcement

As many of you may know or have noticed the main Administration and Support of the J2-M172@FTDNA Project by Chris Rottensteiner since February 2017 has declined considerably, caused by considerably less free time which makes volunteer working  on the daily and weekly tasks impossible at the same pace as I did from 2012 to 2016 . My fellow Co-Admins in J2 […]


J2a-Z6048: refinement in the no-Caucasus J2a* clade

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 […]


Refinement for J2b2a-M241 (including L283,Z622,Z2447,Z2444)

Just a short content post about a refinement in the most important J2b subclade. The smaller Z2447,Z2444 Asian subclade (in terms of discovered subclades) can bee seen in the post image. The broader L283,Z622 European subclade state can be downloaded as a PDF. L283, CTS5649, CTS5382, Z622, Z612, Z615, Z616, Z617, Z607, Z638, Z594, Z597, Z592, Z582, Z585, Z587, Z588, […]


J2b2b-PH1648,Z2455,Z2454 refined: Y18044,CTS8204 & Z42941>Z42983

One of the oldest paragroups of J2b gets a little refined by cross-analysis of the known samples and the new YFull sample SRR2098211 Qatar which should form an ancestral haplogroup with the Jewish subcluster Z42983. It is not known if the PGP29 sample is also of known Jewish ancestry but a BigY match to B12464 is and shares at least […]


possibly J2b1-M205 basal structure defined: CTS1969,CTS5338,YP13,PH4306,PH1089,Y22066

Further analysis of NextGenSequences at YFull (see yfull.com/tree/J-M205/) combined with results from scientific studies (SNP, VCF & BAM results) has revealed a more consistent and hopefully informative basal substructure for J-M205 (see tree.j2-m172.info/?Hg=J2b1) then what was available at the latest major update: J2b-M205>PH4306: a little substructure for this isolated lineage. See also yfull.com/tree/J-M205/ It seems likely that the many remaining […]


ancient Zagros J2b* Iran (Abdul Hosein, Early Neolithic) – Broushaki et al.

New J2b data from Broushaki et al. 2016 (BAM raw data): AH2 West Iran Early Neolithic (8205–7756 BC): one of three individuals. From Tepe Abdul Hosein located South East of Ganj Dareh in Central Zagros. Broushaki et al. not assigned, Genetiker J2b-M12* Own analysis: J2b-M12(xCTS560,Z620). Coverage is low but ok. Of 40 J2b SNPs 10 had positive (derived) calls and […]


first ancient J2 from Iran (Mesolithic, Copper Age) and Levant (Bronze Age) – Lazaridis et al. first farmers

The dataset of the huge Lazaridis et al. 2016 paper is available for download (Reich Lab, BAM raw data). Great that the authors released the data before formal publication and even before peer review. Those three new study samples have J2 Y-DNA: I1293 North Iran Mesolithic (HotuIIIb): 1.5-2 year old individual. From Hotu Cave located in the foothills of the […]


J2a1-PF7413(xPF7415): refinement and new subclade Z40257, Z40258 1

In spring 2015 the articles J2a-L26* SNP found: Z6064? New seldom clade J2a-PH890 and Structure for the J2a-SK1363 clade (including Montgomery, etc. clusters) explained the knowledge about the so far mainly European Z35789, Z35788 subclade. The Montgomery Ireland/Scotland Kits 182443/YF02153, 37060 had known BigY results then. Kit N63471/YF03987 Hunt England later allowed to split the tree into Z35789, Z35788 > […]
