Inferred to overlap with: Df(3R)Po4.
Recessive lethal. Dominant flightless phenotype.
The flightless phenotype but not the recessive lethality of Df(3R)ea-5022rx1 is rescued by Tm2+tΔ-2500. Heterozygotes show disruptions in the periphery of the myofibrils of the indirect flight muscles, and the core of the myofibril is reduced to 21 +/- 3.0 thick filaments.
Mutant embryos respond to injected purified polarizing activity (spz), and produce polarizing activity themselves.
Embryos produced by ea4/Df(3R)ea-5022rx1 females are strongly dorsalised.
