Df(3L)ri-79c embryos show defects in tracheal cell migration.
Deficient embryos show an uninterpretable mutant midgut phenotype.
Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.
Dominantly causes tergite defects in less than 50% of run3 heterozygotes.
Heterozygosity for Df(3L)ri-79c results in 0.9% X chromosome nondisjunction and 1.1% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.
Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.
Heterozygous embryos sometimes have gaps (consisting of patches of naked cuticle) in the denticle belts.
Homozygous mutants embryos show a failure to form a ventral furrow. The mesoderm primordium is internalised late.
No second site non-complementing phenotype with zipEbr and zipmhc-c6.1.
Severe morphological defect.
Shows dominant enhancement of dominant haltere phenotype caused by Ubx195 and Ubx9.22.
Shows no maternal enhancement of dpphr4.
The Df(3L)ri-79c chromosome acts as a dominant weak 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).
The number of midgut constrictions is variable in homozygous embryos.
