    Flies heterozygous for the deletion do not show a Minute bristle phenotype.

    The Df(2L)hk-UC2 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).
