GO:0045138	Definition	The morphogenesis of the tail tip in nematode worms to form a copulatory structure. The most posterior hypodermal cells in the tail define a specialized, sexually dimorphic compartment in which cells fuse and retract in the male, changing their shape from a tapered cone to a blunt dome.
		The process by which the anatomical structures of the tail tip are generated and organized. Morphogenesis pertains to the creation of form. The tail tip undergoes morphogenesis to form a copulatory structure. The most posterior hypodermal cells in the tail define a specialized, sexually dimorphic compartment in which cells fuse and retract in the male, changing their shape from a tapered cone to a blunt dome. As in, but not restricted to, the roundworms (Nematoda, ncbi_taxonomy_id:6231).
