(a–c) – Distribution of Eniclases individuals along principal component (PC) scores of genetic variation based on the analysis of the RAD dataset (PC1 for clades A, B and C 15, 12.1, and 5.6%, respectively; PC2, 15.0, 10.1, and 5.1%, respectively). (d–f) – Plots of inferred individual’s admixture coefficients based on sparse non-negative matrix factorization (sNMF) implemented in R package LEA for the clades of closely related Eniclases species as defined by phylogenetic analyses. Other K clusters are shown in Supplements along with entropy graphs. The analyzed dataset contained 8.76 × 10⁴ loci and 6.5 × 10⁵ SNPs
