Construct: A heat shock promoter drives expression of Ccap\Xdh.
Ccap\Xdhhs.PP is a suppressor of abnormal eye color phenotype of ry506
Ccap\Xdhhs.PP is a suppressor of pigment cell phenotype of ry506
Expression of Ccap\Xdhhs.PP using heat shock in ry506 animals results in flies with wild-type eye pigmentation.
