M205, PF7316, CTS560,

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 […]

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 […]

exogenous Roman era York 3DRIF-26 is J2b1-M205 and likely Middle Easterner

The years 2014 and 2015 did provide useful ancient genomes NGS data in an increasing manner (see ancient J2-M172 genomes). For J2 the year 2016 could not begin more exciting: Martiniano et al published a paper about nine ancient genomes from northern Britain: Genomic signals of migration and continuity in Britain before the Anglo-Saxons. As introduction to the sample of interest […]

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 / […]

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  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 […]
