Imprecise excision of the progenitor insertion, P{EP}twfEP3701, removing most of the coding region of twf.
The majority of twf110 mutant animals die as larvae. 1.8% of animals survive to adulthood.
The majority of twf110/twf102 mutant animals die as larvae. 2.2% of animals survive to adulthood.
β lobes of the mushroom body cross the midline in approximately 50% of twf102 and 30% of twf102/Df(3R)su(Hw)7 mutant animal brains. In severe cases, the two β lobes are completely fused. β loves are bifurcated and thickened. 50% of twfEP3701 mutants display unilateral or bilateral loss of the adult mushroom body α lobe.
