Haplotype study J-L26 L250 L1064 PF5169 PF5197 DYS391=9
As everyone can follow in Y-DNA J Project
and J-L26 J2a1/J2a3/J2a4 subclades SNP discoveries news info
the recurrent? SNPs L250.2, L251.2 (first found in E-V13) are in Oct. 2012 tested in most other clades and clusters. It is possible that there was a parallel mutation (or backmutation or multiple gene conversion)
in J2a-L1064 and/or J2a-M68. By this J-L250 (and maybe also M68 and L1064) is under strong investigation and it was the the reason to found this project focusing with the research on a former J2a-L26* cluster (FTDNA2009 J2a4* and now J2a-L1064), the existing J2a-M68 clade (FTDNA2009 J2a4c), J2a-L26*A1 cluster (see J-Project, FTDNA2009 J2a4*) and other near haplotypes.
J2a-L250 is currently downstream of J2a-L26
(FTDNA2009 J2a4 defined by L26=Page55/S57, L27=S396 and probably L927). J2a-L26 is downstream of J2a-M410 (FTDNA2009 J2a defined by M410
Probably in fall 2012 new SNPs between J2a-L26/L27 and J2a-L250/L251 will be available by Advanced SNP Order at FTDNA (Z2224-Z2235?) and by Geno 2.0 testing.
J2a-L250 in Oct. 2012 is still under investigation and has no nomenclature name at FTDNA, ISOGG, Ancestry.com, 23andMe or YCC. FTDNA, scientists and others have anounced to use primarily shorthands like J-L250 or J2a-L250. This project prefers to use haplogroup names like J2a-L250 or J2a-L1064 (indication of major haplogroup and terminal SNP), while the project name is J-L250.
