From: The Mediterranean Sea as a barrier to gene flow: evidence from variation in and around the F7 and F12 genomic regions

Figure 3

PCA plots of the first and second PCs for: (a) All samples; (b) the Old World samples (i.e. excluding Bolivians); (c) the Mediterranean samples only. The percentage of variation explained by each PC is shown in brackets. North African populations are represented by a triangle, South European populations by a square, Native Americans by a diamond and the Ivory Coast by a circle. PC Analyses were based on data from both the F7 and the F12 genomic regions.
