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.
Homozygous Df(1)ED6584 mutant flies are lethal.
Most of the eggs derived from mothers carrying Df(1)ED6584 mutant germline clones are unable to complete meiosis. 91.9% of eggs show an anaphase I-arrested chromosome configuration. Metaphase I arrest appears normal in the mature oocytes.
