Fig. 1.

Representing genome architectures as graphs. Panel (A) shows two genomes, G₁ and G₂, each containing a single chromosome with five to eight genes. Panel (B) shows graphical representation of genomes G₁ and G₂. Merging similar nodes in the genome graphs shown previously results in a new graph, (C). The addition of labels to nodes and edges results in a labeled multi-directed graph, also known as quivers. Panel (D) shows the quiver representation for genomes G₁ and G₂—in this case the colors correspond to the labels of G₁ and G₂. Merging of the two quivers similarly results in (E), the canonical quiver representation of genomes G₁ and G₂
