    Homozygotes die as wandering third instar larvae.

    The Df(2R)Pcl7B chromosome does not act as a dominant 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).

    Heterozygosity for Df(2R)Pcl7B results in 1.4% X chromosome nondisjunction and 1.4% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.

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

    Shows maternal enhancement of dpphr4, dpphr56 and dpphr27, measured as reduction in recovery of doubly heterozygous progeny.

    Uncovers Dsim\jba in D.melanogaster/D.simulans hybrids. Does not uncover Dsim\pm in D.melanogaster/D.simulans hybrids.

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

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

    When heterozygous with wild type, flies carrying the Pcl deficiency show transformation of second and third legs to first legs. Enhances Pcl3
