Imprecise excision of the insertion in bunGE12327, resulting in a deletion that affects bun isoforms A and F; the deletion starts 343bp upstream of the bun A start codon and extends for 2038bp.
Deletion resulting from the imprecise excision of P{EP}bunGE12327. The deletion starts 343bp upstream of the bun A start codon and extends for 2038bp.
Homozygotes die mostly at the larval stage.
bunA-211B/Df(2L)Exel6033 larvae develop more slowly than normal and die during the second and third larval instars.
