Phylogenetic Analyses of Centralized Hemagglutinin Genes. The genetic relationships between the consensus genes and wildtype genes are shown in unrooted neighbor-joining phylogenetic trees. H1, H2, H3 and H5 consensus genes are shown localizing to the center of the tree. Black bars indicate the percent divergence of the HA amino acid sequences. The central tree (dotted line) illustrates the degree of genetic diversity between the HA subtypes.
