Female sterile over Df(1)DEB4D. Eggs from mutant mothers fail to complete meiosis. In 90% of embryos there is no sign of development and no evidence of a female pronucleus. Normal polar body structures are only rarely observed. Most common phenotype is that eggs contain a structure that resembles a nucleus arrested in anaphase. In the 10% of embryos that initiate development, there are defects in preblastoderm nuclear divisions. Divisions are not synchronous. Not all nuclei migrate to the periphery. 5% of embryos develop far enough to secret cuticle. Head involution fails during gastrulation. In embryos where head involution is partial, the most prominent defects are shortening of the lateralgraten and fusion of the ventral arms of the cephalopharyngeal skeleton.
