NOT in combination with other aberrations
83% of hemisegments show an RP2 to RP2sib cell fate transformation in homozygous embryos.
Deficient embryos show a mutant midgut phenotype: midgut primordia do not migrate from terminalia.
Heterozygosity for Df(2L)30A-C results in 2.1% X chromosome nondisjunction and 2.5% 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.
Intermediate second site non-complementing phenotype with zipEbr and zipmhc-c6.1: malformed phenotype penetrance 25-75%.
Midgut primordia do not fuse, but remain at the anterior and posterior of the yolk mass in homozygous embryos. The hindgut is somewhat shorter than normal. The Malpighian tubules bud out but do not elongate.
Shows a dose-sensitive interaction with pbhs.PB.
Shows no maternal enhancement of dpphr4.
The Df(2L)30A-C 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).
