Principal Component Analysis of the Spanish and Portuguese samples from POPRES using the haplotypes found with HaploPOP. The haplotypes were built from 447,245 SNPs using a window size of 150 kb. For constructing haplotypes, the training sets consist of the Portuguese and Spanish individuals (Panel a) or a mix of Portuguese and Spanish individuals in both sets ‘A’ and ‘B’ (Panel b)
