Connected components of the breakpoint graph of SDs. (A) A connected component of the breakpoint graph of SDs in the hg19 assembly of the human genome formed by 38 SD-blocks. (B) The same connected component in the contracted breakpoint graph formed by 26 SD-units. Numbers on each edge show the length and complexity of the corresponding SD-unit. We colored edges of the graph to visualize the relationships between SD-blocks and SD-units.
