A sequences had high in-group mutual homology scores — the

orner of Figure 7.22. The homology alignment scores for the five

uences show slightly divergent similarity. It means that these five

s had a greater degree of dissimilarity, which was consistent as

demic has lasted for over one year. The GISAID has collected all

s submitted in this period. Each submitted sequence has an

nied submission date. For each country, the submission dates

racted for each sequence and the submission date of the first

d sequence was used as the beginning date. The rest of submission

re subtracted by this first submission date. This generated a

named as the time lag. Each country had one time lag value. This

variable was treated as the dependent variable and 64 3-mers were
