34% of embryos derived from females carrying one copy of dlRHR.Hsp83.T:Ecol\lacZ are dorsalised and do not hatch. 95% of the embryos derived from cact7/+ females carrying one copy of dlRHR.Hsp83.T:Ecol\lacZ are weakly ventralised and do not hatch. More than 99% of the embryos derived from Df(2L)TW119/+ females carrying one copy of dlRHR.Hsp83.T:Ecol\lacZ are weakly dorsalised and do not hatch.
Expression causes dominant negative dorsalisation of the embryo.
