71C2-71C3;72B1-72C1
Inferred to overlap with: Df(3L)BSC833.
The distal half of the salivary gland turns but the proximal half does not in embryos homozygous for Df(3L)XG5 by stage 14.
The Df(3L)XG5 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).
