Fig. 2: Genetic clustering using SNPs and HHS testing with orthologous genes.
From: Backcrossing to different parents produced two distinct hybrid species
A Bar plots indicative of assignment probabilities from ADMIXTURE analysis of 184 transcriptomes assuming numbers of clusters (K) 2 to 6. B Principal component analysis (PCA) plots showing the first three principal components. C Relationships between P. likiangensis species complex (PLSC), P. brachytyla s.s., and P. wilsonii (using P. breweriana as outgroup) according to ML analysis of 3305 orthologous gene sequences identified by OrthoMCL as having a ratio of 1:1:1:1. And the proportion of each topology is based on the ortholog groups. D ML-bootstrap network for 3305 orthologous gene trees generated by PhyloNet after runs allowing 0, 1, or 2 reticulations. Reticulations are shown in blue with inheritance probabilities. Note: Only trees with branch bootstrap values > 70% were analyzed. E KS age distributions for 1:1 orthologs between the PLSC and P. brachytyla s.s. and P. wilsonii. PLSC: P. likiangensis species complex.
