Two-dimensional scatterplot showing the location of the selected duplication (red diamond) versus the full dataset (grey dots). Each point represents an mtDNA rearrangement with the 5’ breakpoint on the x-axis and the 3’ breakpoint on the y-axis.

Circular mtDNA plot specifying the location of the duplicated region (black bar).
Length distribution of the duplicated region in the selected duplication (red bar) versus the full dataset (grey bars) .The cases were grouped 100-nt windows.
