Figure 4.

Bayesian phylogeny of Dscam exon 17 homologs. Only branches with posterior probabilities greater than 0.5 are shown (probabilities are shown beside each branch). Roman numerals (I and II) and colored branches denote the two major clades (magenta, and cyan, respectively). Subclades (A and B) of Clade I are denoted with colored text labels, orange (prefix_01) and black (prefix_02). Subclades (A and B) of Clade II are denoted with colored text labels, blue (Dscam_suffix) and green (DscamL_suffix).
