Figure 3. Cluster analysis plots of the All_M20 dataset with the same color scheme for each lineage as previous figures unless otherwise stated. a) STRUCTURE plot with an optimal K value of 8 (𝚫K=8), showing a large amount of admixture. A. microunicolor and A. unicolorA retain their color from previous figures while A. unicolorB does not due to additional clusters (see key for lineage coloration). b) PCA plot, showing significant cluster overlap of A. unicolorB lineages. c) VAE plot, displaying no clear distinctions among A. unicolorB lineages and d) VAE results with encoded mean (µ) and standard deviation (σ) for each sample.
