hypomorphic allele - molecular evidence
Excision of P{(-loxP)(-FRT)Flipper2}apMM and concomitant gene conversion has resulted in a 397bp deletion and insertion of a GFP reporter driven by a minimal heat shock promoter, bracketed by a pair of inverted attP sites.
In apc2.73c/apDG3 mutant flies only small wing and haltere stumps form.
