Df(3R)Dr-rv1 embryos show defects in tracheal cell migration.
Heterozygosity for Df(3R)Dr-rv1 results in 0.0% X chromosome nondisjunction and 0.0% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.
Homozygous embryos have abnormal gut morphology.
Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.
Retains at least the w+mC of the progenitor P{Hs-Sox70D} insert.
All limits from polytene analysis (FBrf0091344)
