A 24.0kb deletion at the inv locus ( 2R:7357207-7381178 , genome release v5).
Scer\FRT-mediated recombination between two progenitor insertions has resulted in the deletion of the genomic sequence between them.
inv[+]/invΔ24 is an enhancer of visible | adult stage phenotype of enΔ1.5
Df(2R)Δ110, invΔ24 has visible | adult stage phenotype
enΔ1.5, inv[+]/invΔ24 has visible | adult stage phenotype
Df(2R)Δ110/+, enΔ1.5, inv[+]/invΔ24 has visible | adult stage phenotype
inv[+]/invΔ24 is an enhancer of adult abdomen phenotype of enΔ1.5
Df(2R)Δ110, invΔ24 has wing phenotype
Df(2R)Δ110, invΔ24 has wing vein phenotype
enΔ1.5, inv[+]/invΔ24 has posterior crossvein phenotype
Df(2R)Δ110/+, enΔ1.5, inv[+]/invΔ24 has wing vein phenotype
Df(2R)Δ110/+, enΔ1.5, inv[+]/invΔ24 has adult abdomen phenotype
Majority of invΔ24/Df(2R)Δ110 flies display wing posture defects (held-out wings) and about 16% also show wing vein abnormalities.
enΔ1.5 homozygous mutants carrying one copy of invΔ24 show wing posture defects (held-out wings), extra wing vein material at the posterior crossvein and the penetrance of abdominal hemisegments fusion defects observed in enΔ1.5-only mutants is increased to 100%.
enΔ1.5 heterozygotes homozygous for invΔ24 show fully penetrant hemisegment fusion phenotype but only about 14% percent of them also display aberrant wing posture. The full double homozygotes all hold-out their wings in addition to the fusion defects and also exhibit an ectopic wing vein material phenotype of similar severity and penetrance as the enΔ1.5,invΔ24/enΔ1.5,+ flies.
enΔ1.5,invΔ24/Df(2R)Δ110 adults show fully penetrant wing posture, wing vein as well as hemisegment fusion defects.
