Indeed, there are not many commands with "duplicate" in their names.
One example:

  (defun picture-duplicate-line ()
    "Insert a duplicate of the current line, below it."
    (interactive)
    (save-excursion
     (let ((contents
            (buffer-substring
             (progn (beginning-of-line) (point))
             (progn (picture-newline 1) (point)))))
       (forward-line -1)
       (insert contents))))
