Fig. 6

Phylogenies include homologous partial duplicates (highlighted in blue) on S. exigua, S. purpurea Z, and homologous regions on the intact copy of RR17 in S. exigua, S. purpurea, and P. trichocarpa. The patterns suggest that the partial duplicates on Z and Y each have a single origin. Bootstrap support > 70 is indicated. The tip labels are formatted as Species-Chromosome-Copy number. Sp: S. purpurea; Se: S. exigua; Pt: P. trichocarpa. C refers to the intact copies of RR17.
