General Information
Term genital disc ID (Ontology) FBbt:00001784 (Fly Anatomy)
Definition Imaginal disc that gives rise to the internal and external genitalia, analia and adult hindgut (Cohen, 1993). It is located just anterior to the anus of the larva, connected to the epidermis by a thick stalk at the posterior of the disc (Epper and Nothiger, 1982).[ FlyBase:FBrf0037847 FlyBase:FBrf0064789 ]
