Variegated w expression that can be suppressed by Su(var)2-1 mutations.
w variegation leads to clones of phenotypically wild-type cells in a mutant background. This phenotype is suppressed by crmsa.
The presence of a single copy of Mow mutation significantly increases the amount of pigment in both males and females, both MowEMS and Mowgamma suppress position effect variegation.
Males exhibit a mottled eye phenotype. Variegation is enhanced by E2f1164.
Position effect variegation of w is moderately suppressed by mutations of Rm62. Suppression by allele of Rm62 is additive, heteroallelic escapers are more strongly suppressed than heterozygotes.
Males display a variegated eye phenotype, red spots are clones of cells expressing the w gene and white spots are w inactivation due to heterochromatinisation. Males also heterozygous for Trl13C the eye colour is almost white, indicated a more frequent inactivation of the w gene.
Intermediate variegating line. Eyes show strong white mottling with red patches on a white background.
