Heterozygous females produce embryos with defects in segmentation and head structure, and also a variable and occasionally very high proportion of undeveloped eggs. Bicaudal embryos are not seen.
Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans
Shows no maternal enhancement of dpphr4
Homozygous lethal. Heterozygotes show occasional nicking of the wings.
Midgut development of mutant embryos is wild type.
Homozygous embryos are very abnormal compared to wild-type. Differentiation of Malpighian tubule material is variable.
Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2
Does not exhibit dominant flightlessness.
Enhances BicD in heterozygotes (Mohler and Wieschaus, 1986) homozygous lethal
