Embryos from mv^ros/Df(3L)R-G7 mothers show enlarged yolk granules. A small fraction shows aberrant mitotic spindles of different sizes associated with varying amounts of DNA, abnormal chromosome segregation and multiple centrosomes often in chains; the majority reaches the syncytial blastoderm stage but exhibit localized MTOC inactivation and loss of contact between nuclei and centrosomes at the cortex, leading nuclei to sink into the interior of the embryo (nuclear fallout); in live imaging, cortical migration of nuclei is followed by an abrupt flow of cytoplasm from within the embryo toward the surface, displacing the cortical nuclei toward the embryo's poles and leading to the surfacing of yolk nuclei, which normally get left behind in the embryo's interior.

Stage 4 embryos from mv^ros/mv¹ mothers show multiple centrosomes often in chains
