Fig 1. FBti0019985 is inserted in the first intron of cbx gene and it overlaps with CG18446 5’-UTR region.

Schematic representation of the genomic region where FBti0019985 is inserted: chromosome 2R: 9,864,510–9,875,072. FBti0019985 is shown in red. Black boxes represent exons and white boxes represent the 5’-UTRs and the 3’-UTRs. Primers used to check for the presence/absence of FBti0019985 are depicted as black arrows (FL, R, and L; see Materials and Methods).
