Phenotypic Data
In combination with other aberrations
Strongly suppresses the zeste phenotype in a z1 w11E4; Tp(1;2)TE35B homologue.
NOT in combination with other aberrations
Chromosome acts as a strong trans-suppressor of a physical interaction between tandemly duplicated copies of w+, an interaction that is required for the suppression of genes by z1.
