    Other Comments
     

    The Df(2L)b87e25 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 suppressor maps to the tip of 2L rather than to the site of the deficiency. In addition, the deficiency chromosome fails to complement lethal mutations of l(2)gl.

    (Mason et al., 2004)

    "irradiation" was stated as tentative. "spontaneous" was stated as tentative.
