Fig. 4. The relationship between sli, insc and nb. Embryos in A-D
are double stained for Eve (green) and Insc (red) and in E and F, for Eve. A-D
show one hemisegment each; E and F, one segment each. Anterior is up, vertical
lines mark the midline. Scale bars, 10 µm. (A,C) Wild-type embryos, Insc is
asymmetrically localized (arrowhead) in GMC-1 and GMC1-1a. (B,D) sli
mutant embryos, the localization of Insc in GMC-1 and GMC1-1a is
non-asymmetric. (E) nb mutant embryo. In nb both the
daughters of GMC-1 adopt a sib fate (arrows). (F) sli, nb double
mutant embryo; both the daughters of GMC-1 adopt a sib fate.
