  • a Expressed as a percentage of expected number; n = number of flies scored.

  • b Obtained by weighing two to three sets of 20 males of each genotype/vial; values represent the average of at least two independent vials; values typically varied by <5% between vials.

  • c Based on measurements of 10 female wings of each genotype.

  • d Calculated by counting wing bristle density from 10 female wings in a 37,500-μm2 rectangle between wing veins three and four, just distal to the anterior cross-vein, and converting to area/cell.

  • e Hypothetical number of intervein cells in one surface of the wing blade, obtained by dividing wing blade area/cell area.

  • f Measurements were taken separately for banΔ1/TM2 flies from each vial, and these were used as control reference values (i.e., 100%) within each vial; the range of values obtained is indicated.

  • g Significantly smaller than banΔ1/TM2 siblings, P < 0.001.
