Astonishing J1 results

The lab reviewed the pherograms for kits M3704 and M4004.
> Upon re-evaluation of the pherograms for each sample, the lab
> reassigned the value of 18 to DYS#388 for sample M3704.
> This change is now reflected in our database and a new certificate for

Thanks, Gulf. This also makes more sense now to have the third person clustered with you and your cousin, since he's 17. I haven't had a chance to look up the article Jim referred me to, but although YCAII may be useful in clustering, I'm still betting on DYS388 as a stronger basis for J1 subgrouping.

Excavating Y-chromosome haplotype strata in Anatolia. Cinnioğlu C, King R, Kivisild T, Kalfoğlu E, Atasoy S, Cavalleri GL, Lillie AS, Roseman CC, Lin AA, et al.

Strictly speaking, they identified a cluster of J1 with DYS388=13 in Anatolia and the Caucasus. Whether the few Bedouin, Arab, and European cases are descended from the same common ancestor or are from independent mutations, I don't know.
