    Ts(Y;2Lt)GT2+Ts(YSt;2Rt)A80/Df(2L)b84a2 and Ts(Y;2Lt)a15+Ts(YSt;2Rt)A80/Df(2L)b84a2 animals usually die as pharate adults, escapers have crippled legs. Df(2L)A400/Df(2L)b84a2, Df(2L)el14/Df(2L)b84a2 and Ts(Y;2Lt)el4+Ts(YSt;2Rt)R15/Df(2L)b84a2 animals die as pharate adults with crippled legs. Df(2L)TE35B-12/Df(2L)b84a2, Df(2L)TE35BC-8/Df(2L)b84a2 and Df(2L)TE35B-1/Df(2L)b84a2 animals have an early lethal phenotype. Df(2L)el16/Df(2L)b84a2 and Df(2L)fn2/Df(2L)b84a2 animals usually die as pharate adults, rare escapers have crippled legs and show an "elbow" phenotype. Df(2L)el28/Df(2L)b84a2 animals often do not survive to adulthood, those that do have have an "elbow" phenotype. Df(2L)TE35B-6/Df(2L)b84a2 animals often do not survive to adulthood, those that do have an "elbow" phenotype.

    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.
