The Keilin's organs are absent in mutants. Homozygous mutant clones induced the larval period fail to survive.

Embryos hemizygous for Df(1)C52 have a stronger lateral pentascolopidial chordotonal organ (lch5) phenotype than btd alleles, developing up no more than two scolopidia per chordotonal organ, and often developing none.

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

Shows no maternal enhancement of dpphr4.

Acts as a dosage sensitive maternal modifier of run : causes tergite defects in greater than 50% of run3 heterozygotes.

Deficient embryos show a variably penetrant mutant midgut phenotype: incomplete constriction formation.

Heterozygous larvae have a negative photokinetic stimulus indice similar to wild type and transheterozygotes with lphA2 have an extremely high indice, they are blind.

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

More than six-fold reduction in sex ratio and significant levels of female lethality is observed when in combination with Sxlf1. Female lethality is also reduced when in combination with da1 but restored when in combination with emcML.

Mutant wing position of fliF and flw uncovered in deficiency heterozygotes.

Other Comments

flw alleles are lethal over Df(1)v-L15 but viable over Df(1)C52, with a flap-wing phenotype.
