Homozygous embryos exhibit reduced hindgut and anal pads, primary cause is ectopic cell death in the primordia. Transheterozygotes with byn2, byn3, byn4 and byn6 allow some (1-25%) survive to adulthood, no escapers are obtained from transheterozygotes with byn5. Escaper adults appear morphologically normal but females are sterile (no eggs in the egg chambers have progressed beyond stage 7 of ovarian development). Escapers usually die 1-2 days after eclosion.
P{Trg20} can rescue the lethality of byn1/Df(3L)vin4 transheterozygous embryos.
