Fraction of alternative alleles specific to viral strains in admixtures. The allelic fraction of exclusive mutations, measured from all the eight replications, was compared against the ratio of viral strains, separately for the Hong Kong (a) and the Washington (b) strains. The admixtures contain 0%, 1%, 5%, 10%, 25%, 50%, 75%, 90%, 95%, 99%, or 100% of either strain (the x-axes). The allelic fraction of exclusive mutations was plotted on the y-axes. Areas of the plot with many overlapping points appear as dark clusters, and the dotted diagonal line indicates 1:1 concordance. For both the strains, the Pearson’s correlations (R) are indicated
