amorphic allele - genetic evidence
Blocks 1, 3, 4 and 5 of 5 conserved blocks of the ap enhancer region have been inserted into the attP site in TI{TI}apattPΔEnh, from which all 27kb of enhancer sequences have been removed.

No wing tissue is formed in apC1345/apDG3 flies.
Defects are seen at the dorsoventral boundary of apC1234/apC1345 mutant flies.
