Genetic mapping information

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

    In combination with other aberrations

    Inferred to overlap with: T(Y;3)G75.

    NOT in combination with other aberrations

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

    Lethal in combination with: Df(3R)BSC140. Inferred to overlap with: Df(3R)BSC140.

    Df(3R)Espl3 embryos show defects in tracheal cell migration.

    The Df(3R)Espl3 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).

    Strong phenotypic reversion: 250--350 facets per eye. Severe embryonic phenotype: loss of ventral, lateral and majority of dorsal cuticle. Viable when heterozygous with a Dl allele.

    Embryonic lethal, extreme neurogenic phenotype.
