Breakpoint(s) molecularly mapped
Selected on basis of variegating position-effect on bw+t30 in P{bw+1111}65Fx2 : intermediate level cis-inactivation of P{bw+1111}65Fx2 and trans-activation of P{bw+1111}65Fx2 but had no detectable effect on any other ectopic bw+t8.4 or bw+t30 copy. Male sterile. Recessive lethal or semilethal.
Induced on basis of trans-inactivation of P{bw+1111}65Fx2
All limits from polytene analysis (FBrf0054058)
