    Analysis of two-cell mutant clones in the sensory organ precursors of the leg indicates that bract induction is normal when the inner (sheath and neuron) cells are mutant, and that bracts are not induced when the outer cells (shaft and socket) are mutant. Most single-cell mutant clones fail to induce bract cells, while single-cell mutant clones in the shaft cell have no effect on bract cell induction.

    Shows no maternal enhancement of dpphr4.

    The Df(2L)pr-A14 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), but this is a false positive result (the suppressor is not within the bounds of the deficient region) because the region of the deficiency is covered by one or more nonsuppressing deficiencies.
