Examples of orthology. A part of the tree of the cluster 15 is shown. The tree is calculated with CLUSTALW, with 1000 bootstrap replicates. The bottom pair of orthologs illustrates one-to-one type of orthology. The top group shows many-to-many type of orthology in which two worm proteins are orthologous to two human proteins (and two mouse proteins). Sequences with a dot in the name are worm proteins.
