For the Purposes of This Question, Assume That Being Rh

For the purposes of this question, assume that being Rh+ is a consequence of D and that Rh - individuals are dd. The ability to taste phenylthiocarbamide (PTC) is
determined by the gene symbolized T (tt are nontasters). A female whose mother was Rh - has the MN blood group, is Rh+, and a nontaster of PTC, and is married to a man who is MM, Rh -, and a nontaster. List the possible genotypes of their children.
