Phenotypic Data
In combination with other aberrations
z1 w11E4; Tp(1;2)TE35B/Df(2L)b81a1 strongly suppressed for zeste.
Df(2L)b81a1/Df(2L)A446 viable Df(2L)b81a1/Df(2L)A446 noc phenotype
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.
