Summary of site-by-site analyses. The figure shows the positive or negative selection in human and avian influenza, and differences in consensus sequences between the hosts. Amino acid positions under positive and negative selection are shaded in red and blue, respectively. Sites under significant positive and negative selection are shaded in dark colors, while light colors indicate no significance. Triangles indicate sites where the consensus amino acids are different between human and avian influenza.
