Fig. 2From: Fast ancestral gene order reconstruction of genomes with unequal gene contentBreakpoint graph BP(A,B) of circular genomes G A =(1,−3,5) and G B =(1,2,3,4), with adjacency sets A={1h3h,3t5t,1t5h} and B={1h2t,2h3t,3h4t,4h1t}. Edges of A are green, and of B are blue. There is one AA-path and two AB-pathsBack to article page
