Table 3 Comparison of flavivirus heatmaps. The number of differences in third nucleotide bias (color, not magnitude) between heatmaps for specific flavivirus genomes is shown. The two insect specific viruses (Aedes and Culex) and two viruses that cause disease in humans (Dengue and Yellow fever) are also compared to the Flaviviridae heatmap.
