Break at 93D maps approximately 45kb upstream of the Hsrω transcription unit.
Only the distal tip of the salivary gland turns in embryos homozygous for Df(3R)e-R1 by stage 14.
The Df(3R)e-R1 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).
Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.
No second site non-complementing phenotype with zipEbr and zipmhc-c6.1.
Normal development and heat shock-induced expression of the 93D puff are unaffected. The amide responsivity of the chromosome is normal. Dosage compensation is abolished as is the effect of β-alanine levels on its heat shock inducibility.
Shows no maternal enhancement of dpphr4.
Dominantly causes tergite defects in less than 50% of run3 heterozygotes.
Midgut development of mutant embryos is wild type.
Homozygous embryos have no amnioserosa.
Df(3R)e-R1/+ heterozygotes show normal responses to sugars and to other taste stimuli.
