J2-M172

Y chromosome haplogroup J2 (J-M172) research: variation, distribution, frequency. Y-DNA paternal ancestry.


J2a-Z6064(xZ6063) confirmed and new split of PH4959,PH4856 (upstream) and PH4099,PH890 (downstream).

See earlier post: J2a-L26* SNP found: Z6064? New seldom clade J2a-PH890 I have done analysis on the new BigY result of 410707 Qatar. He splits the haplogroup so far shared only of 14919/YF03482 Fryer and Pal-5257 Palestinian into PH4959,PH4856 (shared) and PH4099,PH890 (unshared). So the current path from J2a ancestor down to 14919 now is: J2a PF4610>L26>Z6064>PH4959>PH890 See Research tree link […]


Z39600, Z39603: third split under J2a-M319, so far Iberian

Analysis of two BigY SNP reports of FTDNA allowed to refine the M319 subtree. Kit N96398 Pastrana Advincula shares 48 SNPs with an anonymous 1000 Genomes sample from Spain: HG01781. Kit 280709 shares 44 of those SNPs and additionally two more with HG01781 only. I pre-registered the SNPs and defined haplogroups Z39600,Z39603 and Z39632,Z39622. The latter needs confirmation trough more […]


More terminal position of former J2a-L26* Cluster F*

Position found trough a Y-STR67 match not in the J2 project being J-Y7708: J2a-L26>PF5087>PF5116>Z2227>Z6065>Y7708>Z39478?(xM47,P81) One of the last bigger haplotype clusters existing at the begin of 2013 (before Geno 2.0) has found an informative place. See one of my earliest studies figshare.com/articles/J2a_M410_subclades_and_clusters_overview/106387 Thanks to the early J2 haplotype cluster researchers Bonnie Schrack​, Angela Cone​, wo did the founding grouping. Surnames […]


Huge YSEQ update: 253 Subclades of J2 (J-M172) all in one Sanger Sequencing SNP Panel

Sanger Sequencing is is the reliable technology still used by forensic labs and to certify variants on the genome with high accuracy and is also accepted by ISOGG as most reliable SNP certification. The trained Y-chr scientist and experienced lab-director Thomas Krahn together with his wife Astrid has founded YSEQ based in Berlin/Germany at the of 2013 which is leading […]


J2b2a1-L283 origins by diversity and subgroups with focus on Jewish lineages

The early Neolithic split of J2b2a-M241 (YFull 9700 ybp) in to the modern western (L283, Balkans) and eastern (Z2444, India) subclades is detected since at least a decade trough testing of the M241 SNP in scientific studies. According to the current YFull L283 samples the lineages expanded sometime earlier then 5200 ybp, while the Asian lineages expanded since 7100 ybp. This […]


Bekada et al 2015 have published their paper “Genetic Heterogeneity in Algerian Human Populations”. In the present Algerian study only one J2a -M410 was found in North-west Oran1. Combined with earlier studies 8 J2 samples out of 305 total (Y-STR19 haplotypes + major Y-SNPs, S1 Table). By comparison there are 54 J1-M267 samples. IMHO another puzzle piece making early J2 expansion over Northwest Africa to Iberia/Europe unlikely. Other routes seem to be better expansion vectors.


J2a-Z6065: still much to discover for M47, P81, Z7532, etc.

Z6065 was first discovered in the 1000 Genomes Project data by Magoon et al 2013 in three Punjabi samples, one of them M47. In May 2014 the FGC Y-Elite result of KVRKP S.Italy allowed to discover a further split defined by the SNPs Z7532, FGC15782/Y13893, etc. and of the subclade Z7553, Z7503 shared only by two of the Punjabi samples.

FTDNA J2 Haplogroups & SNPs September 2015

FTDNA J2 Tree 17th September 2015 edited to show important SNPs from SNP Packs also included in J2-M172 Research Tree simplified Y-DNA Haplotree Created in partnership with Haplogroup J-M172 This lineage originated in the northern portion of the Fertile Crescent where it later spread throughout central Asia, the Mediterranean, and south into India. As with other populations with Mediterranean ancestry […]


FTDNA J-M172 SNP Pack (xM67,L24) Beta release

Suggestions for members of the J2-M172 Project@FTDNA: 109 SNPs downstream of M172, see J2-FTDNA-SNP-pack_2015-09-09_and-research-tree.PDF optimized for all currently researched subclades except M67 and L24 (will have their own SNP Pack) recommended for kits who won’t invest in NGS (BigY) and like to get a good value for 1/5 of the BigY price recommended for kits without SNP testing who do […]


J2a2-PF5050,PF5053: refinement based on analysis of Sardinian and Kuwaiti data

The publication of Francalacci et al. 2015 Sardinian samples 826-835 as well the BigY result of 208140 Kuwait allowed further refinement of the J2a2 subclades which is very needed since not many Y-NextGenSequences in this Haplogroup are known. Earlier ancient and modern genomes allowed the discovery of  J2a2-PH3085,SK1403: Ancient Altai, modern Uygur and Turkish. Sardinian 826-828: form the Z28317,Z28324 clade […]
