A few rdx5 homozygote embryos hatch, but none survive beyond first instar.
Germline clones (lacking both maternal and zygotic rdx) of rdx5 do not generate eggs.
rdx5 homozygous clones are the same size as their wild-type counterparts in eye and wing imaginal discs.
Wings filled with unmarked rdx5 clones (28 of 40 wings) exhibit a mild elongation of the anterior compartment.
rdx5 pupal ommatidia, at 36-42 hours of pupation, exhibit misaligned primary cells (40% of ommatidia) that sometimes fail to enclose cone cells (6%), as well as reduced numbers of cone cells (4%), inappropriate numbers of lattice cells (56%), ommatidial fusions (2%), and misplaced bristles (19%).
