Figure 4. . Representation of the mutational distances calculated for the 2 selected primer sets overlaid on the coronavirus phylogenetic tree. Each oval represents grouping of members contained within it; numbers next to the group indicate the maximum distance between any 2 members of the group. Distances are computed as the base 10 logarithm of the geometric average of the pair-wise probabilities for any given pair of base compositions.
