FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
Embryos derived from females carrying homozygous germ line clones fail to produce a coherent cuticle. Cellularisation appears to be aberrant in these embryos, as preblastoderm nuclei do not migrate properly to the plasma membrane.
