Fig. 7. Ice is important for cell death induced by rpr, hid, grim
and loss of Th, but not Nc overexpression. (A-J)

photoreceptors (blue) form a regular array in the wild-type adult eye (K).
These cells are largely absent in the eyes of flies expressing Nc, in
the presence (L) or absence (M) of Ice. Animals homozygous for
Ice
1 lack zygotic but not
maternal Ice.
