Construct: w expression is governed by a fragment of Dvir\en promoter extending from -2.9kb to -1.5kb upstream of the transcription start site.
Suppression of w+mC expression in homozygotes, eye colour is lighter than heterozygotes.
The suppression of eye colour is dependent on the proximity of the two copies of the transposon, either in cis or trans.
