Figure 5.
A screen shot of the gene tree page at Ensembl for the INS (insulin peptide) gene. This shows two independent duplications in rodents (giving rise to Ins1 and Ins2 genes) and teleost fish. Duplication nodes are shown as red squares whereas speciation nodes are in blue. The green bars to the right provide a graphical view of the multiple alignment, showing partial gene structures in hamster (Cavia p.), cat (Felis c.), and rabbit (Oryctolagus c.), due to their low coverage status.
