Dp(1;2)4FRDup/Df(1)JC70 viable Dp(1;2)4FRDup/Df(1)ovoG6 viable Dp(1;2)4FRDup/Df(1)RC40 lethal
Rescues the reduced male viability associated with the In(1)M3 chromosome.
Generation described in Salz, Genetics 130: 547--554. This duplication can be carried in males because, unlike the parental aberration Dp(1;2)w+64b, it is deleted for the male diplolethal region at 3F.
