    South Asian J2 from 1000 genomes

    The Yfull team analysis of the 1000 genome samples are invaluable additions especially for the south asian population where commercial testing is only on low level .
    The subclades of the J2 found in south asians was much of a mystery and i have wondered whether it is similar to west asians .the following link have the analysed J2 samples list

    Good amount J2a samples belongs to J-PF5197 which is a brother clade to the big J-L24 clade .
    3 samples belong to J-F312 which is a subclade of previously known J-M68 which seems restricted to south asia (?) . Few samples belong L25 clade too .

    The PJL have some recently introduced subclades from west asia like J-M67 .

    The case of J2b2 is intresting . The south asians (Z2432) sits on a completely different branch with respect to european one(L283) .So it could be older branch which made way to south asia and got isolated there ,though we need some samples in between (some iranians or central asians ) .

    Guys with more expertize in this please chime in with your views

    Yes: J2 1000 Genomes samples from South Asia are very welcome to expand our knowledge about subclades and distribution.
    In J2a-PF5197 project under results there is a list of positive and predicted positive samples:

    The clade seems to have a more complex expansion history then M67 (or the ancestral PF5116) and maybe even then L24 and I expect much of the diversity of subclade PF5174 is not yet discovered (so far only samples from Indus area and "Atlantic Europe" are confirmed).
    Particularly interested in: DNA/Admixture from Historical Tyrol, Central Alps and related/connected populations; Y-DNA J2a-M67-L210, J2a-PF5197-PF5169, R1a-M17, R1b-U106-Z372; mtDNA J1b1b, J1c1d2-A11884G, U5a2b2-G10685A, U5b1b1-b-T16192C! Projects: Hidden Content , Hidden Content , J2a-PF5197, ISOGG Wiki, GenWiki (german)
