Chromosomes bearing small deletions are valuable tools in Drosophila genetics. We have investigated a method for efficiently constructing precise chromosomal deficiencies. Two P transposable elements were positioned within a progenitor strain at the sites of the desired deletion endpoints. Deletions spanning the two transposons were recovered at high frequency when P element transposase was expressed in these flies, but only if the flanking P elements were in a cis rather than a trans configuration. Appropriate progenitor strains can now be constructed to delete virtually any chromosomal region by utilizing an extensive collection of lines containing single P element insertions throughout the Drosophila genome.
