In combination with other aberrations
Df(2L)x528/Df(2L)GpdhA embryos show a loss of neuroblasts NB1-1, NB2-5 and NB2-4. This loss is much more pronounced in odd-numbered than even-numbered abdominal segments. However, the loss is similar to mid mutants, suggesting that the it is deletion of the mid gene and not the H15 gene that is causing the phenotype.
Inferred to overlap with: Df(2L)x528.
Df(2L)GpdhA/Df(2L)x528 larvae show a loss of denticle belts; denticle rows 1 to 5 are frequently lost in odd-numbered segments, whereas even-numbered segments show milder defects. Df(2L)H15-x4/Df(2L)GpdhA larvae show a weak loss of denticles phenotype.
Enhances position effect variegation at the w locus caused by In(1)wm4, C(1;YL)wmMc or T(1;4)wm5 and position effect variegation at the y locus caused by In(1)y3P.
Lethal in combination with Df(2L)cl7. Lethal in combination with Df(2L)Gpdh78. Lethal in combination with Df(2L)Gpdh75. Lethal in combination with Df(2L)cl1. Lethal in combination with Df(2L)cl2.
NOT in combination with other aberrations
Heterozygosity for Df(2L)GpdhA results in 8.0% X chromosome nondisjunction and 2.2% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.
Shows no maternal enhancement of dpphr4.
Dominantly causes tergite defects in less than 50% of run3 heterozygotes.
Midgut development of mutant embryos is wild type.
Homozygous embryos are very abnormal compared to wild-type. The hindgut is short and broad, and the Malpighian tubules do not elongate.
Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.
Enhance mottling in wm4.
