[QUOTE]Originally posted by X-Ras: [QB] [QUOTE]Originally posted by Evergreen: [qb] [QUOTE]Originally posted by X-Ras: [qb] [QUOTE]As far as I know about the Siwa, paternally they are E-V6 and B-M106, I'm not sure what E-DYS271 one is, maybe its E3a(?), but Siwa have it at a percentage of 6%... [/qb][/QUOTE]Evergreen Writes: It would be of interest to know which sub-clade of E3a was found in Siwa and other parts of the Eastern Sahara and Nile Valley. This area of research is still in its infancy in comparison to the delineation of E3b*. The lower frequency of E3a in the Siwa oasis area could relate to limited population subsistence potential during the mid-holocene dry phase. Potential Saharan populations packing would have been greater along the Nile Valley than in the oasis areas where more ancient hunter-gather populations retained land. Evergreen Posts: Sub-populations within the major European and African derived haplogroups R1b3 and E3a are differentiated by previously phylogenetically undefined Y-SNPs. Hum Mutat. 2007 Jan;28(1):97 Single nucleotide polymorphisms on the Y chromosome (Y-SNPs) have been widely used in the study of human migration patterns and evolution. Potential forensic applications of Y-SNPs include their use in predicting the ethnogeographic origin of the donor of a crime scene sample, or exclusion of suspects of sexual assaults (the evidence of which often comprises male/female mixtures and may involve multiple perpetrators), paternity testing, and identification of non- and half-siblings. In this study, we used a population of 118 African- and 125 European-Americans to evaluate 12 previously phylogenetically undefined Y-SNPs for their ability to further differentiate individuals who belong to the major African (E3a)- and European (R1b3, I)-derived haplogroups. Ten of these markers define seven new sub-clades (equivalent to E3a7a, E3a8, E3a8a, E3a8a1, R1b3h, R1b3i, and R1b3i1 using the Y Chromosome Consortium nomenclature) within haplogroups E and R. Interestingly, during the course of this study we evaluated M222, a sub-R1b3 marker rarely used, and found that this sub-haplogroup in effect defines the Y-STR Irish Modal Haplotype (IMH). The new bi-allelic markers described here are expected to find application in human evolutionary studies and forensic genetics. [/qb][/QUOTE]I'm not clear on the E3a subclade they may have, but they do have B-M109 which is of great interest and 1% of E-M81. Haplogroup is rare to nil in Berber speakers exept for the Siwa.
