A fragment of W cDNA is cloned downstream of a GMR promoter sequence.
WGMR.cLa homozygous flies exhibit ablated eyes. Flies heterozygous for autosomal insertions of P{GMR-hid.L} exhibit similar eye sizes in each sex. Flies with X-linked insertions of P{GMR-hid.L} also show little difference in eye size between the sexes. In most cases (hemizygous) male eyes are only slightly smaller than heterozygous female eyes; both sexes exhibit a small range of sizes that minimally overlap.
hidGMR.cLa has eye phenotype, non-enhanceable by msl-2Hsp83.PK/msl-2[+]
hidGMR.cLa has eye phenotype, non-suppressible by msl-2Hsp83.PK/msl-2[+]
WGMR.cLa/+; msl-2Hsp83.PK/+ flies are identical to WGMR.cLa/+ flies.
