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.
Sister centromeres do not separate from each other during mitosis in mutant larval brain cells.
Sister chromatids separate prematurely in san1 Sseunspecified double mutant larval brain cells, as they do in san1 single mutants. Sister chromatids separate prematurely in eco1 Sseunspecified double mutant larval brain cells, as they do in eco1 single mutants.
