Figure 2From: Gene order in rosid phylogeny, inferred from pairwise syntenies among extant genomesSteps in constructing breakpoint graph. Construction of the breakpoint graph. Left: Genomes G1 and G2, with "-" sign indicating negative polarity. Middle: Vertices and edges of individual genome graphs. Right: Cycles in completed breakpoint graph.
