Dye coupling between the TTMn and GF

Genotype	TTMns^2-a	GFs filled	% coupled

↵F2-a Only those specimens that showed heavy TTMn staining could be satisfactorily scored.
↵F2-b Controls were P[GAL4] element alone (18 specimens) and w, Biocore (eight specimens); we observed no difference between the groups, and therefore they are combined.
