Dear visitor: We still need some more time to fully setup the new J2-M172 Haplogroup Research.
Please be patient when you encounter unfinished areas.

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

This speculative discussion is focused on the Y-Haplogroup J2a, but the ancient DNA in combination with known history and the modern distribution suggests to include other Haplogroups (Hg) for a better analysis. The post is intended to provide a basis to discuss contrasting hypotheses. This post was motivated by reading the latest (preprint) paper on […]

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  […]

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) where 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 […]


J/J2 fusion under way @ FTDNA

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 […]

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 […]


J2 Y-DNA Project @FTDNA History 2007-2013

The “J2 Y-DNA Project ” was founded by Costa Tsirigakis and Angela Cone in 2006 and until 2013 has done considerable research in the J2 area, mainly STR-Cluster research to provide an answer to the question if sub-clades can be reliably predicted from extended haplotypes.
