A simplified schematic showing the putative genomic composition of the novel H6N1 and H6N2 reassortant avian influenza viruses identified in this study. The eight gene segments (from top to bottom) in each virus are PB2, PB1, PA, HA, NP, NA, M, and NS. Each colour represents a separate source background. Eight genotypes are listed here. The six different colours represent separate virus backgrounds. The illustration is based on nucleotide-distance comparisons and phylogenetic analyses
