Comparing spatial maps of human population-genetic variation using Procrustes analysis - PubMed (original) (raw)

Figure 1:

Procrustes analysis of genetic and geographic coordinates in Europe, based on data from Novembre et al. (2008). (A) Geographic coordinates for 36 countries. (B) Procrustes-transformed plot of the first two principal components of genetic variation. The plot is centered at the geographic centroid of the populations. Individuals are represented by two- and three-letter abbreviations, and circles represent the centroids of the PCA coordinates for individuals from a country. Abbreviations are as follows: AL, Albania; AT, Austria; BA, Bosnia-Herzegovina; BE, Belgium; BG, Bulgaria; CH, Switzerland; CY, Cyprus; CZ, Czech Republic; DE, Germany; DK, Denmark; ES, Spain; FI, Finland; FR, France; GB, Great Britain; GR, Greece; HR, Croatia; HU, Hungary; IE, Ireland; IT, Italy; KS, Kosovo; LV, Latvia; MK, Macedonia; NL, Netherlands; NO, Norway; PL, Poland; PT, Portugal; RO, Romania; RS, Serbia and Montenegro; RU, Russia; Sct, Scotland; SE, Sweden; SI, Slovenia; SK, Slovakia; TR, Turkey; UA, Ukraine; YG, Yugoslavia. Population labels follow the color scheme of Novembre et al. (2008). The figures are drawn according to the Gall-Peters projection.
