    In combination with other aberrations

    Dominantly enhances position effect variegation at the w locus caused by In(1)wm4, C(1;YL)wmMc or T(1;4)wm5 and position effect variegation at the y locus caused by In(1)y3P. Position effect variegation at the w locus is not seen when Df(2L)E110 is combined with In(1)wm4rv5, In(1)wm4rv6 or In(1)wm4rv26.

    NOT in combination with other aberrations

    The Df(2L)E110 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(2L)E110 results in 2.6% X chromosome nondisjunction and 0.5% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.

    Wild-type clones made in the ovaries of a mutant female, are significantly larger than clones of heterozygous mutant cells. This size difference is greater in clones initiated at 48 hours after egg laying (AEL) than 2 hours AEL.

    Enhance mottling in wm4.

    Homozygous lethal.

    Enhances position-effect variegation of In(1)wm4. Recessive lethal.
