Figure 1: Schematic for the whole phylogenetic tree of actin genes in the seven species using nucleotide alignment of actin domain (a). Orange (human), Dark Cyan (chimpanzee), Blue (gorilla), Wine (orangutan), Cyan (gibbon), Magenta (rhesus monkey), and Green (marmoset). The Red clades represent the orthologous groups. The representative actin domain phylogenies for (b) clades in the complex group displayed multicopies from the same species, (c) clades in the complex group which lost copies from some species, and (d) clades in the orthologous group. The tree was built based on the neighboring-joining method with a Jukes-Cantor model.
