The absence of the cranial three-fifths of the vaginae of male mice carrying the gene, Testicular Feminization, provides strong support for the view that vaginal epithelium is of dual origin, the cranial three-fifths being of Mullerian in origin and the caudal two-fifths being derived from the urogenital sinus.
