[61A1-61A1];[61B1-61B1];
A set of isogenic deficiency stocks created by FLP-induced recombination between FRT-carrying transgenic insertions; molecularly defined deletion endpoints correspond to initial location of the progenitor insertions. Initial core set of 209 isogenic deletions provides ~60% euchromatic genome coverage.
61A1;61B1
Terminal deletion of the 3L chromosome, capped by the tip of the X chromosome.
