Phenotypic Data
In combination with other aberrations
Does not suppress the zeste phenotype in a z1 w11E4; Tp(1;2)TE35B homologue.
NOT in combination with other aberrations
Chromosome has no effect on the physical interaction between tandemly duplicated copies of w+ and z1, despite having breakpoints within the critical region.
