Deletion of 5' sequences up to -305bp.
Construct: Deletion of 5' regulatory site at -305bp.
Includes all the w sequences of w+mC plus extra w upstream sequence to the 5' end of the BgB enhancer element.
No change in wild type eye pigment in the presence of Mowgamma.
Pigmentation in eyes and testes is wild type.
w+mSC has phenotype, non-enhanceable by Low1
w+mSC has phenotype, non-suppressible by Low1
The eye colour of flies carrying w+mSC on either the X chromosome or an autosome is unaffected by a single copy of Low1.
