Figure 6 shows the average number of mismatches over time, grouped by the genomes sampled The results of this study also demonstrate that each primer target develops a different number of mismatches over time The mutations that lead to mismatches between gene PCR primers and their targets reflect the sequence evolution of the consistent with the observed increasing number of mismatches over time, and shows that evolution of SARS-CoV-2 genomes is of the RdRp gene, primer target creates a disproportionate number of mismatches when compared to genomes sequenced within ./cache/10_1101-2020_12_26_424429.pdf ./txt/10_1101-2020_12_26_424429.txt
