Aclass diagramis a graphical representation of these relationships2. For example, this diagram shows the relationships betweenCard,DeckandHand. The arrow with a hollow triangle head represents an IS-A relationship; in this case it indicates that Hand inherits from Deck. ...
An example of this is the ABO blood groups where the allele A and allele B are both expressed. If a child inherits an allele A from their mother and an allele B from their father, the individual has blood type AB. Autosomal Recessive Inheritance Autosomal recessive inheritance means that ...

With the help of inheritance, you can define a general class that defines some functions to perform some basic operations and extend that to other classes to inherit those functions. Let’s understand it through the diagram. In this example, we have Dog and Cat, and both are different animal...
Set the BaseClass property of the derived class to the name of the base class.To set inheritance between two domain relationshipsCreate a domain model that has at least four domain classes, for example, Book, FictionBook, Author, and FictionAuthor. Create two embedding relationships, as follows...
