Cluster ensemble results. Significance (P < 0.005) of clustering solution is shown by the purple line. For each pair of animals, the p value is determined as 1 minus the percentile of their similarity in the null distribution. Significant clusters (1–4) are highlighted by the primary CrERV determining the clustering solution (in parentheses), with the cluster color (blue, green or orange) corresponding to their lineage in Figure 2. Cluster branches are color-coded by geographical region (NE = blue; NW = red; W = orange; SW = yellow, SE = green; Utah = gray), with “populations” indicated by the numbers at the end of each branch. In some cases, multiple CrERVs determine the clustering solution as indicated by the arrows for specific nodes.
