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 […]


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 […]


Y-chromosome Haplogroup J-M172 subclades update with primary SNPs

Combined J2 Phylogeny from almost all available public and DTC sources. Included are ca. 200 informative subclades (pre Middle Age) as well as more recent haplogroups (low-diversity/Middle Age or Clans/Surnames). The phylogeny is available as Tree with primary SNPs (searchable PDF) and Spreadsheet with details for the selected primary SNPs. This data is an output of the constantly updated online […]


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 […]


Y-DNA J-Project @FTDNA History 2006-2013

The “J-Project” was founded by Bonnie Schrack in 2006 and until 2013 has done considerable research in the J2 area, mainly SNP research (Z385-Z639, Z2220-Z2397) from public Y-Sequences to improve the Haplogroup-Phylogeny and provide updates to the ISOGG tree (accepted also by scientists). To backup important news from this time period and make them available for search here, a copy […]
