    static void CreatePrefab()
    {
        GameObject clone  = PrefabUtility.InstantiatePrefab(Selection.activeObject as GameObject) as GameObject;
    }

    [MenuItem("Examples/Instantiate Selected", true)]

    static bool ValidateCreatePrefab()
    {
        GameObject go = Selection.activeObject as  GameObject;
        if (go == null)
            return false;

        return PrefabUtility.GetPrefabType(go) == PrefabType.Prefab || PrefabUtility.GetPrefabType(go) == PrefabType.ModelPrefab;
    }
