"Iran: Tricontinental Nexus for Y-Chromosome Driven Migration.

Due to its pivotal geographic position, present day Iran likely served as a gateway of reciprocal human movements. However, the extent to which the deserts within the Iranian plateau and the mountain ranges surrounding Persia inhibited gene flow via this corridor remains uncertain. In order to assess the magnitude of this region's role as a nexus for Africa, Asia and Europe in human migrations, high-resolution Y-chromosome analyses were performed on 150 Iranian males. Haplogroup data were subsequently compared to regional populations characterized at similar phylogenetic levels. The Iranians display considerable haplogroup diversity consistent with patterns observed in populations of the Middle East overall, reinforcing the notion of Persia as a venue for human disseminations. Admixture analyses of geographically targeted, regional populations along the latitudinal corridor spanning from Anatolia to the Indus Valley demonstrated contributions to Persia from both the east and west. However, significant differences were uncovered upon stratification of the gene donors, including higher proportions from central east and southeast Turkey as compared to Pakistan. In addition to the modulating effects of geographic obstacles, culturally mediated amalgamations consistent with the diverse spectrum of a variety of historical empires may account for the distribution of haplogroups and lineages observed. Our study of high-resolution Y-chromosome genotyping allowed for an in-depth analysis unattained in previous studies of the area, revealing important migratory and demographic events that shaped the contemporary genetic landscape."

 The reasult is very intresting showing that iranian has at least %50 genes from central asia including %18  of mongolian origin in the north.

Also Iranian have % 4 african genetic at south.

  The reasult shows thatIranians are mostly from central asian origin, could be Aryan or Turkic immigrants.

 

 

 

I don't want to say anything about the research itself but representative group is considered to be more than 30 individuals in any biological research. So, 150 individuals is more than enough.

 

I agree with that logic.

 

Wait a bit, man, one cannot produce a complete study.  The truth is infinite  

 

 

I just wonder why they still present the results if they know the sampling isn't complete. As the people in that field, they should know how the sampling should be done. Even if they don't, then the editors?

 

As far as I understood, the research focused on answering the question of : the extent to which the deserts within the Iranian plateau and the mountain ranges surrounding Persia inhibited gene flow via this corridor remains uncertain, so what they are concerned is two groups (although there are varieties among respective groups within itself), then for me the sampling is more that enough, or am I missing a point here?
