Figure 2From: On the distribution of cycles and paths in multichromosomal breakpoint graphs and the expected value of rearrangement distanceConstruction of the breakpoint graph for a circular identity genome I and a circular genome A. The adjacencies of I are represented by black edges and those of A by grey edges. Unvisited nodes are white, visited ones are black. To build a perfect match (circular genome A) only two operations are possible: (a) Create a cycle; (b) Merge two paths.Back to article page
