Fig. 1From: Variation at the DRD4 locus is associated with wariness and local site selection in urban black swansBlack swan DRD4 and SERT protein alignments. Protein alignment are for (a) exon three of the dopamine receptor D4 and (b) the serotonin transporter, and are aligned with orthologous sequences from various bird species. Dots indicate matching amino acids relative to the black swan and dashes represent gaps. Protein sequence identifiers include the species name and GenBank accession numberBack to article page
