When P{P-Sal}Pak3P-Sal is present, the w gene of the P{lacW}Dplac insertion variegates, resulting (in a w- background) in an eye that is mostly white with a few patches of red ommatidia. This P-element-dependent silencing of P{lacW}Dplac is dominantly suppressed by Df(3R)ry27.

The Df(3R)ry27 chromosome does not act as a dominant suppressor of telomeric silencing (assayed using the effect of the chromosome on the eye colour phenotype of flies carrying "P{wvar}KR3-2", a stable "brown-red" variant of the P{3'WP-2,wvar}2Lt insertion).

Homozygous embryos show abnormal dorsal closure and tracheal formation.

Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.

Homozygous viable. Transheterozygotes with B52ED produce very few adult progeny and those that survive have head defects that resemble those observed by in extreme Dfd mutants. This effect is due to an uncharacterised genetic element on the Df(3R)ry27 chromosome.
