    In combination with other aberrations

    Df(3L)Pc-MK/Df(3L)Pc-cp2 animals carrying PctPa develop into normal looking larvae which fail to hatch. Larvae removed from the vitelline membrane are immobile, but respond to pokes from a needle with slow, uncoordinated movements. The larval muscle pattern is indistinguishable from wild-type. The SNb nerve ends at muscle VO1, failing to innervate the VL1 muscles. RP3 motor axons fail to innervate muscle VL3 and VL4.

    NOT in combination with other aberrations

    Approximately 83% of heterozygous males have ectopic sex combs on the second and/or third legs, indicating a transformation towards first leg.

    Weak second site non-complementing phenotype with zipEbr and zipmhc-c6.1 : malformed phenotype penetrance 10-24%.

    Initially showed maternal enhancement of dpphr4, but effect not due to disruption of discrete element within the deficiency. The enhancing activity seems to be recombinationally separable from the deficiency.

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

    Fails to form a 78C puff.

    Deficient embryos show an uninterpretable mutant midgut phenotype.

    Mutation changes the level of w expression in ph-plac+3 flies; eye colour is darker.

    Heterozygosity for this deletion suppresses the mutant ovarian phenotype of ovoD2.
