The
Df(3R)Dfd13 chromosome acts as a dominant moderate suppressor of telomeric silencing (assayed using the effect of the chromosome on the eye colour phenotype of flies carrying "P{w
var}KR3-2", a stable "brown-red" variant of the
P{3'WP-2,wvar}2Lt insertion).
Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of
ovoD2.
Reduced-sex-comb phenotype in heterozygotes.
