In combination with other aberrations

Weakly suppresses the zeste phenotype in a z1 w11E4; Tp(1;2)TE35B homologue.

NOT in combination with other aberrations

Chromosome acts as a weak trans-suppressor of a physical interaction between tandemly duplicated copies of w+, an interaction that is required for the suppression of genes by z1.

Semilethal with noc. Males and females homozygous viable and fertile with strong noc and osp phenotypes

Reported to delete Adhr in error; see FBrf0141768 for correction.

nLA178 chromosome carries an independent translocation, T(2;3)CA3, that can be removed by exchange.
