FLPase mobilisation of P{XP}d06635 (located 6.5kb upstream of the Frq1 transcription start site) and PBac{WH}Frq2f06131 (located in the first intron of Frq2 completely removes the Frq1 gene locus and the first exon of the Frq2 coding region.
Site-specific FLP/FRT recombination between P{XP}d06635 and PBac{WH}Frq2f06131 was used to create a deletion of Frq1, Andorra, and part of Frq2.
