Well, consider that there are thousands of P-element mutant lines available in various labs. Most of these carry mini-white as a marker, and as a result have eye colors ranging from barely off-white to completely (apparently) wild-type. Presumably visual acuity will correlate roughly with color intensity, and so this may offer a way of "fine-tuning" your assay. Of course, you have to be certain that the lines bearing the inserts aren't otherwise messed up, at least for your purposes, but you'd have to do this with any other mutant line as well. Good luck, Christopher Jones (jonesc@cshl.org) -- Chris Jones (jonesc@cshl.org) .
