Figure 2From: Expression and evolutionary divergence of the non-conventional olfactory receptor in four species of fig wasp associated with one species of figThe maximum parsimony tree of Or2 genes from fig wasps. The MP phylogram was constructed based on 1st + 2nd codon positions. The reliability of each tree node was assessed by bootstrap proportions with 1000 replications. Branch lengths are proportional to change.Back to article page
