From: The complexity of selection at the major primate β-defensin locus
Substitution rates and selection measured in two branches of the tree relating mammalian β-defensins. Each graph shows Ka (black circles), Ks (white circles) and significant positive selection across the sequence (midpoints of 3 codon windows) encoding the mature peptide. The graphs display the analysis for branches C and F in Figure 1, a relatively recent and an older branch demonstrating positive selection respectively. The positions of the beta strands and alpha helix in DEFB1 are indicated.
