||(primary source p.7160 right column 3rd paragraph:) "Many replicate cultures are grown from small mutant-free inocula until roughly half have experienced a mutation, and the cultures are then scored for average population size and for mutants."
||"Mutation rates in DNA-based microbes: Rates of spontaneous mutation in this class of organisms were last surveyed in Drake (1991) and are summarized in Table 4 using a few updated values for genome sizes. Unlike the experimental and theoretical limits to the accuracy of the RNA-virus values, the DNA-microbe values were determined in well-studied systems using robust calculations, and the individual values are likely to be accurate to within two-fold. Table 4 shows that µb and G vary inversely and smoothly over nearly four orders of magnitude while µg remains constant. Given the paucity of general, constant values in evolutionary processes, this particular constant is strikingly robust." For description of parameters see link
