(UPDATE 2015-05-04: three FGC Wael Y-sequences) Since the first Geno 2.0 results were known for the old J2a4i (L198,L433) and the yet uncertified L1064 clusters, we did know they were PF5169(xPF5174) which means positive for PF5169 and negative for PF5174. Since not many J2 subclades have more then two parallel “brother” subclades I suspected that J2a-L198,L433 and L1064 shared some […]
FTDNA J2 Tree 28th April 2015 edited to show important SNP 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 this lineage is […]
I worked trough the evidence for this old J2a clade for ISOGG certification and found new structure: http://tree.j2-m172.info/?Hg=J2a1b Z6049 is equivalent to S18476/SK2198. A new subclade is SK1312 for whom so far all Georgian BigY are positive: 270352, 259005, 258936 Since Z6048 has no coverage in BigY we have to wait until FTDNA is able to complete the BigY of […]
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. […]
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 […]
