In combination with other aberrations
NOT in combination with other aberrations
Chromosome has no effect on the physical interaction between tandemly duplicated copies of w+ and z1, despite having breakpoints within the critical region.
Unstable rearrangement inducing a variety of spontaneous novel rearrangements
Enhances H (Ashburner, 1982). Unstable, transposing and producing shorter derivatives. Homozygous viable.

Notes on Origin
Discoverer
 
Recovered as apparent dp cn bw double recombinant from a test cross of a dysgenic male that was heterozygous for a maternally derived dp b cn bw second chromosome and a paternally derived autosome extracted from a natural population and capable of promoting male recombination.
