Principal component analysis based on the variability of the 14 populations from the 1000 Genomes Project and the Spanish sequenced population. Distances are based on a total of 198 different variant positions in which the sequenced Spanish population presented a reasonable coverage (>10×) and there was at least one variant in an individual. Colors are as follows: European populations in yellow; Asian populations in blue; African populations in purple and American populations in brown. PC, principal component.
