From: Evolution of the avian β-defensin and cathelicidin genes
Positively selected sites in avian β-defensins and cathelicidins. Site-wise rates of synonymous and nonsynonymous substitutions (dN − dS) calculated using FEL are shown (cutoff at 5 for large |dN − dS|). Chicken genes are shown as reference sequence; dashes indicate gaps introduced during alignment with orthologues in other species; mature peptide domains are indicated by grey graph background. Sites under positive selection are indicated by plus signs
