Detection of outlier SNPs along the 10 chromosomes of the genome based on a Principal Component Analysis of mexicana accessions, French teosintes and Spanish teosintes using pcadapt. (A) Projection of accessions onto axes 1 and 2 of the Principal Component Analysis. (B) Manhattan plot of the P values of SNPs with the first principal component of the PCA. The 45 top SNPS having q-values less than 0.1% are displayed in red.
