Figure 2.

Whole genome Maximum Likelihood tree of the 12 sequenced samples and 8 publicly available references. The tree was constructed in IQ-TREE using a transversion model with empirical base frequencies and allowing for invariant sites. The tree was based on the concatenated segments. The pairwise sequence comparison was on average 12,296 bp long. The sequenced samples are shown with orange tips, while the references are shown with green. Ultrafast bootstrap was performed with 10,000 replicates, and values ≥ 95% are shown on the nodes. The scale bar shows genetic distance (SNPs/site). The tree is rooted with the Glesvær isolate for illustrative purposes.
