Sgs6 << bk1 << l(3)72Ad << l(3)72Dn << bk2 << ms(3)72D

Genetic mapping information

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

Breakpoint(s) molecularly mapped

Comments on Cytology

Ashburner et al., 1980, D. I. S. 55: 193 reports cytology as 72B1 to 72D12, from cytological analysis it is thought the chromosome is deficient for 72A as well.

Limits of break 1 from polytene analysis (FBrf0098597) Left limit of break 2 from inclusion of l(3)72Dn (FBrf0082216) Right limit of break 2 from non-inclusion of ms(3)72D (FBrf0082216)

    In combination with other aberrations

    Dominant scutellar bristle phenotype is increased in trans to Df(3L)A27 to around 48%.

    NOT in combination with other aberrations

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

    The Df(3L)th102 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).

    Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.

    Dominantly causes tergite defects in less than 50% of run3 heterozygotes.

    Mutation changes the level of w expression in ph-plac+3 flies; eye colour is darker.

    Adults heterozygous for Df(3L)brm11 or Df(3L)th102 have a high frequency of duplications of the anterior scutellar bristles (around 24%).

    Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.

    Heterozygotes for Df(3L)th102 and Df(2L)JK12 have thin bristles and weakly outstretched wings.

    "72A2;72E12" was stated as revision.

    Used in D.melanogaster/D.simulans hybrids to map at least four non-overlapping regions on the D.simulans 3R that have effects on the species difference of cuticular hydrocarbon profile.

    "71F3--71F5;72D12" was stated as revision.

    Reduces the expression of homeotic genes.
