The reconciled tree. This tree was viewed as the evolved P/A tree inside the accession tree. The accession tree was shown in blue and the P/A tree in black. At the edges of branches were the accession names, countries and 8 regions where they were sampled. Most of the P/A tree vertices matched the accession tree vertices (dark blue ellipses) particularly in each geographic clade, which meant the P/A polymorphic pattern was associated with individual variation.
