Imprecise excision of P{EP}D1EP473, resulting in a small inversion with breakpoints at the site of the original P{EP}D1EP473 insertion and within the ird1 gene. D1 RNA is detectable in In(3R)D11A/Df(3R)D1C12w- ovaries.
In(3R)D11A/Df(3R)BSC24 adult flies are not viable.
Inferred to overlap with: Df(3R)BSC24.
