Figure 4From: Approximating the edit distance for genomes with duplicate genes under DCJ, insertion and deletionAn example of adjacency graph with duplicate genes. (a) Structures of the two genomes. (b) Adjacency graph. (c) A decomposition with 2 cycles. (d) A decomposition with only 1 cycle. Diamonds and rectangles represent ghost adjacencies, and circles represent normal adjacencies.Back to article page
