In combination with other aberrations

Df(1)N71/Df(1)N19 double heterozygous females have reduced viability; only 8% survive compared to control flies. Viability is recovered if the Df(1)N71/Df(1)N19 females also carry SxlM1. The viability of Df(1)N71/Df(1)RA2 or Df(1)N71/+ female progeny derived from a cross between Df(1)RA2/+ females and Df(1)N71/Y males is severely reduced.

NOT in combination with other aberrations

No second site non-complementing phenotype with zipEbr and zipmhc-c6.1.

Deficient embryos show an uninterpretable mutant midgut phenotype.

Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.

Heterozygous females exhibit reduced viability and fertility.
