Multiple Inheritance is not allowed in C#?

In Cambridge dictionary meaning for inheritance is "particular characteristics received from parents through the genes". That means a child or children can receive genes from their parent. Obviously a child or children can have one parent only not multiple parents.

C# well attuned to real world scenario. That means a child or children can have one parent only, not multiple parents. Likewise in C# also inheritance is treated like real world child parent relationship. That mean a child class can only inherit from its parent class.
