This is an important and very interesting study. Dienekes has a bit to say on it as well. Can anyone access the haplotypes from this paper? My comp does not seem to be allowing me to do it. I want to run some of the J2-M172 haplotypes through a predictor.

Thanks for posting this. Please find the Y-STR's in this link (http://www.sendspace.com/file/r248ub).

^No problem my friend. I will have to try another computer tomorrow as this Mac seems strange to me. It will not let me open the download. I am wondering if the J2-M172 haplotypes found among the Hill Tribe Forager groups are J2a or J2b2 mainly? The haplotype predictor may help in this.

Most of the Y-DNA J men belong to J2-M172(xJ2a1-M47, J2a3-M68). One needs to check this, but I'm fairly certain that the root SNP markers (J2a-M410 and J2b-M12) haven't been used here.

Also interesting to note there are two J*-M302 (12f2.1 equivalent SNP), both belonging to different demographic groups (Kattunaickan and Parayar), with both also having wildly divergent STR haplotypes (only 3/17 match).

Thus, another point of interest is ascertaining whether they have any relation to the Socrotra J*-12f2.1. I might look into this in the next few days (have a 18 hour journey ahead of me!).

^I was able to get a look at the haplotypes but the STR markers at the top were all jumbled up. If I knew which STR markers were used and the order they were used in I would be able to check the haplotypes. You are correct that the M410 and M12 SNPs were not tested in this study. That is why so many of the males in this study are just listed as M172. In reality most of them are going to be ether M410 or M12 I should think.

Oh and good luck on your journey! :)

J Man,

Here is the STR list in the order shown within the spreadsheet:

DYS389I DYS389II DYS390 DYS456 DYS19 DYS458 DYS437 DYS438 DYS448 DYSGATAH4 DYS391 DYS392 DYS393 DYS439 DYS635 DYS388 DYS426

^Thanks man! Most look to be J2b for the HTF samples most of which in reality are probably J2b2.

[Thread moved to Other Y-DNA Haplogroup section]

I took a stab at locating some genuine J*-M209 haplotypes but couldn't find any. The Cadenas study showing Socotra J* only tested for SNP's, which is a shame.
