Fig. 3: Principal component analyses of native and introduced Mimulus guttatus.

From: Population genomic and historical analysis suggests a global invasion by bridgehead processes in Mimulus guttatus

Fig. 3

Principal component analysis (PCA) of 474 individuals of Mimulus guttatus from both native and introduced populations genotyped at 1498 binary SNP loci. A Scatterplot of the first two principal components (PC2 vs. PC1). B Scatterplot of first and third principal components (PC3 vs. PC1). Colours indicate sample regions. An interactive 3D figure with individually labelled data points is available at: https://mvallejo6.github.io/mimulus_voyage/. A visualisation of the first 200 principal components (cumulative variance explained = 90.9%) projected in two dimensions using Uniform Manifold Approximation and Projection for Dimension Reduction (UMAP)77 is shown in Supplementary Fig. 4.
