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 […]

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 […]

J2a2-PH3085,SK1403: Ancient Altai, modern Uygur and Turkish

The huge Allentoft et al. 2015 research with low-coverage genomes from 101 ancient humans from across Eurasia included two males from Altai Iron Age (900 BC to 1000 AD) in the same J2a2 haplogroup (see Altai archaeology). Even more intriguing is that the ancient genomes share unique Y-SNPs with two modern samples: one Uygur and one Turkish, currently best named […]

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 […] optimal  global  discrimination capacity  based  on  a  strongly  reduced  set  that  includes  only  the  most  resolving  Y-SNPs. […]

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 […]
