FLP-mediated recombination between the two progenitor insertions has resulted in the deletion of sequence between them, removing the entire CLIP-190 gene and a C-terminal portion of Rpb11.
lethal | recessive
The lethality of the Df(2L)CLIP-190 chromosome is rescued by Rpb11Ubi.PB, indicating that the lethality is caused by an effect on Rpb11.
