rdx4 is a complex rearrangement of the region upstream of exon 5, generated by imprecise excision of rdx1 insertion P{PZ}mei-P1903477.

lethal (with rdx6)
lethal - all die before end of first instar larval stage
some die during first instar larval stage
viable | germline clone
rdx4 homozygotes hatch, but the sluggish, slow-growing larvae seldom survive beyond the first instar.
Germline clones (lacking both maternal and zygotic rdx) of rdx4 yield embryos that develop and hatch normally.
rdx1
Based on embryonic and larval lethality, the following rdx alleles can be ranked from strongest to weakest as follows: rdx5 > rdx6 > rdx4 = rdx1.
