hide Comments on Cytology
Lacks 2R heterochromatin.
Most of the centric heterochromatin on 2R is deleted.
Mitotic prophase preparations of Df(2R)M41A10 clearly show that the proximal 2R heterochromatin is missing
Limits of break 1 from polytene analysis (FBrf0053437) Left limit of break 2 from inclusion of RpL38 (FBrf0027524) Right limit of break 2 from polytene analysis (FBrf0049871)

hide Phenotypic Data
In combination with other aberrations
Partially sensitive to segregation distortion by In(2R)SD5.
NOT in combination with other aberrations
Does not cause unconditional lethality in hybrid females when heterozygous with D.simulans chromosome.
Acts as a dosage sensitive maternal modifier of run: causes tergite defects in greater than 64% of run3 heterozygotes.
Heterozygosity for this deletion has no effect on the mutant ovarian phenotype of ovoD2.
Heterozygotes have shorter bristles than wild type flies. Eclosion is delayed by 13 hours.
Heterozygotes show a thin bristled Minute phenotype. Homozygotes do not survive.
Dominant enhancer of variegation.
homozygous lethal Long-bristled Minute; readily classifiable. Enhances variegation of white mottleds and brown Variegateds to same extent as removal of a Y chromosome. Causes abnormal development of hybrids with D.simulans (e.g., melanotic tumors, extra organs, missing organs, death).

The Df(2R)M41A10 chromosome may 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), but the eye colour phenotype in the presence of Df(2R)M41A10 overlaps the eye colour phenotype in a wild-type background so it cannot be unequivocally demonstrated that the deficiency chromosome uncovers a suppressor of telomeric silencing.
"Deletes or disrupts l(2)41Ae" was stated as revision. "Deletes or disrupts Nipped-A" was stated as revision. "Does not delete or disrupt stw" was stated as revision. "Does not delete or disrupt ap" was stated as revision.
Used to enhance variegation.
