Figure 2.
Phylogenetic reconstruction of mouse and human OR genes at the TCR-α/δ locus. Paup (Sinauer Associates) parsimony tree for the six mouse (prefix “m”) and five human (prefix “h”) OR genes at the TCR-α/δ locus is shown. Previously published names for mOR4, mOR5, and mOR6 are shown in parentheses (25). The two human pseudogenes are shown in light gray. Percent nucleotide identities for orthologs are indicated within orthologous clades. Scale bar for branch length (50 nt changes) is shown.
