Fig. 2. The nuclear division and cytokinesis of GMC-1 in sli mutants is symmetric. Embryos in A-D (half segments) are double stained for Eve (red) and spectrin (green). RP2 is indicated by large arrow, sib by small arrow. Scale bars, 5 µm. Anterior is up. Both nuclear division and cytokinesis of GMC-1 are asymmetric in wild type (A,C) while in sli mutants (B,D), they are symmetric and yield two equal sized RP2s at the expense of the sib.
