Figure 1From: Evolution of orthologous tandemly arrayed gene clustersSpecies and gene trees for the three genomes 1, 2, 3. Left: The species tree for three genomes 1, 2, 3. Three orthologous TAG clusters {O1, O2, O3} are identified in the three genomes. The notation j i denotes the i th gene in genome j. Right: A gene tree for the gene family.Back to article page
