The notion of generic extensions of representations of a Dynkin quiver plays a big role inthe study of the structure of the corresponding quantum group. In this paper, we describe the genericextensions of a simple representation by any representation and that of any representation by a simplerepresentation of a Dynkin quiver Q of type D.
