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.
Mutant embryos show very abnormal mitosis with respect to the wild type, starting with the first mitosis. Early nuclear divisions are not completely successful. Spindle and chromosome configurations are very irregular and centrosome behavior is also affected.
