amorphic allele - molecular evidence
opus element insertion at -301 relative to the transcription start site plus a 687bp P-element insertion 581bp downstream of the tub transcription unit.
0.75kb of P-element DNA is inserted 3' to the tub open reading frame.
abnormal dorsal/ventral axis specification | embryonic stage | maternal effect (with tubR5.6)
lethal | maternal effect
tub9/tubR5.6 females produce embryos that span a phenotypic range from severely to moderately dorsalised.
Variable dorsalising phenotype.
P-element excision derivatives have a wild type phenotype.
