In combination with other aberrations

No effect on In(1)wm4h position-effect variegation.

Viable in combination with In(2L)b80c2.

NOT in combination with other aberrations

Heterozygosity for this deletion suppresses the mutant ovarian phenotype of ovoD2.

Chromosome has no effect on the physical interaction between tandemly duplicated copies of w+ and z1, and has breakpoints outside the critical region.
