||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. An example of this process is found in Caenorhabditis elegans.
