May be due to insertion of a ZAM element; an additional ZAM element is detected by in situ hybridisation close to the w gene (which is where RevIII-7b maps) in the RevIII-7bRevIII-7b mutant, while it is absent in the wIR6RevII-7 progenitor strain.
RevIII-7bRevIII-7b is a suppressor of abnormal eye color phenotype of wIR6RevII-7
RevIII-7bRevIII-7b is a suppressor of pigment cell phenotype of wIR6RevII-7
Eye colour: dark brown (with wIR6RevII-7).
Arose as: a suppressor of the wIR6RevII-7 eye phenotype.
