Total mutant frequency multiplied by the incidence of each type of mutation presented in Table 1.
Fold increase induced by PhlP relative to spontaneous mutant frequency.
Total mutant frequency determined in a parallel induced mutant frequency experiment.
Run of six guanines, base 207 to 212 in exon 3; includes all types of mutations as listed in Table 1.
