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.
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.
