In combination with other aberrations

Complements Df(3L)fln1. Fails to complement Df(3L)kto2.

NOT in combination with other aberrations

Df(3L)VW3 embryos show defects in tracheal cell migration.

Heterozygosity for Df(3L)VW3 results in 0.9% X chromosome nondisjunction and 0.0% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.

No second site non-complementing phenotype with zipEbr and zipmhc-c6.1.

Dominantly causes tergite defects in less than 50% of run3 heterozygotes.

Deficient embryos show a mutant midgut phenotype: visceral mesoderm does not develop.

Homozygous embryos do not complete dorsal closure and gastrulation is often abnormal.

Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.

Has a Minute phenotype, presumably due to M(3)76A being deleted.
