amorphic allele - molecular evidence
abnormal neuroanatomy | third instar larval stage (with Df(2R)Pcl7B)
embryonic/larval neuromuscular junction | third instar larval stage (with Df(2R)Pcl7B)
type Ib terminal bouton | third instar larval stage (with Df(2R)Pcl7B)
staur9/Df(2R)Pcl7B larvae have a significantly reduced number of type Ib boutons compared to wild type.
