Isolation and characterization of Df(2R)BSC11 Megan Deal-Herr, Kevin Bogart and Kevin Cook Bloomington Drosophila Stock Center, Indiana University Df(2R)BSC11 was isolated as a P transposase-induced male recombination event involving P{lacW}l(2)s3475s3475 and P{PZ}chn02064. The deletion was isolated as a cn+-bw+ recombinant chromosome from the cross cn1 bw1 females x cn1 P{PZ}chn02064/P{lacW}l(2)s3475s3475 bw1 sp1; TMS, Sb1 P{ry+t7.2=Delta2-3}99B/+ males. Polytene chromosome squashes showed the breakpoints 50E6-F1;51E2-4. Df(2R)BSC11 failed to complement phyl2245, Rpn6k00103, and Asx1.
