Fig. 2From: Frequency of influenza H3N2 intra-subtype reassortment: attributes and implications of reassortant spreadReassortment frequency of the reassortant and non-reassortant lineages. The number of reassortment events in each of the lineages/clades as a function of the number of genomes belonging to that clade. Data points are highlighted in color of their reassortant lineage (see Fig. 1). The top black data point represents the Texas/50/2012 vaccine-associated non-reassortant clade. Inter-clade reassortment events were weightedBack to article page
