Comments

This deletion removes a single ribosomal protein-coding gene (though other genes are also removed).

    In combination with other aberrations

    No effect on In(1)wm4h position-effect variegation.

    NOT in combination with other aberrations

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

    The Df(2L)N22-5 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).

    Heterozygosity for Df(2L)N22-5 results in 0.4% X chromosome nondisjunction and 0.0% fourth chromosome nondisjunction in In(1)FM7/X ; svspa-pol females.
