Averages give an overview of different populations' makeup, but they may mask important variation. Thus, I have decided to present the individual-variation of the various populations included in the Project. You can get a RAR file with all populations here.
Below, I will highlight a few ones. I apologize about the quality of the graphics, but these were generated by a script I wrote which doesn't seem to have the presentation controls of normal "Save As".
First, the Saudis:
You can see, for example, that the West African admixture in this population comes pretty much from 3 individuals, with one of them having a substantial chunk of it. Some individuals have South European or West Asian admixture, while many belong 100% to the Southwest Asian component.
Next, the Ashkenazi Jews:
You can see that some individuals have an excess of the North European component, while others have almost none.
Next, the Burusho:
These appear very homogeneous, with what variation we might expect from random hereditary processes or the limitations of admixture inference.
Next, the Romanians
I've commented on the presence of 2 probable Roma individuals in this population before, and this seems quite evident in this plot.
Finally, the Gujarati:
It is evident that the North European and East Asian element is limited to a few individuals, with most of them appearing to be a "South Asian" and "West Asian" blend. One might speculate that these represent individuals admixed with other subcontinental populations where these two components are more important.
