Spatial principal components analysis (sPCA) of M. sinensis in Japan using 5359 SNPs across 782 individuals from 205 collection sites. (A–C) Interpolation of scores of lag vectors of the first three eigenvectors produced by sPCA. Scores are represented the darkness of greyscale pixels. The percentage of genetic variation between sites explained by each of the three eigenvectors is indicated. (This figure is available in colour at JXB online.)
