Create an entity$-$relationship diagram for a genealogy software package called $$PeopleTree$$ to keep

track of ancestors. Assume that each person will be on a Person table and that one person may have

one biological father and mother as well as an adopted mother and father. The mothers and fathers

must be stored on the Person table as well. Each person should have only one birthplace, stored on

the Place table. Many people may be born in the same place.
