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 […]


J2b-M205>PH4306: a little substructure for this isolated lineage

The diversification of J2b into M205,CTS560,PF7316 and the brother Z575,CTS2622/Z1827 seems to have happened a long time ago (YTree v3.12 16200 ybp) while the diversification of M205 was possibly only 5600 ybp. So this seems a long time of isolation without expansions if no so far undetected splits do exist. Using data from Hallast et al 2014 and Estonian Biocentre / […]


J2b-PH1751,PH2967: brother of Z1297

The analysis of Sicilian, Circassian/Abazin and Greek samples revealed this new ISOGG candidate downstream of Z1296/CTS8995 and parallel to Z1297. Little is known about the further distribution but the best matching haplotypes are Albanian/Macedonian, Austrian and one probably from todays Turkey. Z1296 is currently estimated by YFull YTree v3.12 to have diversified ca. 3,800 years ago. The genetic distance between […]


J2b-CTS3617: southern brother of Z638 detected in Balkans and Italy

Two samples uploaded to YFull allowed a more detailed analysis of this clade so far only marginally known. Parallel to Z638,CTS12554 (father of to the known Z1296/CTS8995) this branch seems to be more southern and was not detected so far in Northwest Europe. Basic structure CTS3617, Y15058/Z34462 {Z38240.} PH1602, PH1601 {PH2350, PH502} [PH3514, PH4583] [(306997/YF02051 Bulgaria YFS 11+10-5)] [(ser-13 Serbia […]
