Figure 3. Correlation between initial growth rate and (A) SNV, (B) small indel, (C) segmental duplication/deletion, and (D) whole-chromosome gain/loss mutation rates across the seven environments.

Mutation rate units are the same as in Fig. 2. Each colored point represents the mean from all MA lines in the corresponding environment, whereas the horizontal and vertical error bars represent standard deviations of the growth rate and mutation rate among MA lines, respectively. The dashed line represents linear fitting on all 166 MA lines, while the grey shaded region shows the standard error predicted by the linear fitting. Spearman’s ρ and Pearson’s r and their associated P-values are based on all 166 MA lines. See also Figure S2 and Tables S4–S5.
