Table 2. Inferred REPIN duplication rates in P. fluorescens SBW25.

Mutation class	Inferred duplication rate ${\lambda }_i$ (× 10−9)a	Scaled duplication rate ${\stackrel{\sim }{\lambda }}_i$ (× 10−9)b	Mean duplication rate (simulation)	SD duplication rate (simulation)
0	10.9	11.3	13.1	2.4
1	7.6	8.1	10.3	2.5
2	6.7	7.1	9.4	2.4
3	−0.4	0	2.0	2.5
4	0.0	0.4	1.4	2.5

^aWe identified the master sequence 5′-ATGTGGGAGGGGGCTTGCCCCCGAT-3′ in the data and inferred the frequency of the different mutation classes. We use the equilibrium of our quasispecies model to calculate the associated fitness values $f_i$ and set $f_4$ to 1, where ${\lambda }_i$ is $f_i-1.$

^bThe scaled duplication rate is: ${\stackrel{\sim }{\lambda }}_i=f_i/\min \left(f_i\right)-1.$
