Polymorphism vs Inheritance - What's the difference?
polymorphism | inheritance |
The ability to assume different forms or shapes.
(biology) The coexistence, in the same locality, of two or more distinct forms independent of sex, not connected by intermediate gradations, but produced from common parents.
(computer science) The feature of object-oriented programming pertaining to the dynamic treatment of data elements based on their type, allowing for an instance of a method to have several definitions. (en)
(mathematics, type theory) The property of certain typed formal systems of allowing for the use of type variables and binders/quantifiers over those type variables; likewise, the property of certain expressions (within such typed formal systems) of making use of at least one such typed variable.
(crystallography) The ability of a solid material to exist in more than one form or crystal structure; pleomorphism.
(genetics) The regular existence of two or more different genotypes within a given species or population; also, variability of amino acid sequences within a gene's protein.

The passing of title to an estate upon death.
(lb) That which a person is entitled to inherit, by law or testament.
(lb) The biological attributes passed hereditarily from ancestors to their offspring.
In object-oriented programming, the mechanism whereby parts of a superclass are available to instances of its subclass.
In biology terms the difference between polymorphism and inheritance
is that polymorphism is the coexistence, in the same locality, of two or more distinct forms independent of sex, not connected by intermediate gradations, but produced from common parents while inheritance is the biological attributes passed hereditarily from ancestors to their offspring.As nouns the difference between polymorphism and inheritance
is that polymorphism is the ability to assume different forms or shapes while inheritance is the passing of title to an estate upon death.polymorphism

- Since 1990 they have found an entirely new role: they promise understanding of how and why our genes are all so different. They hold the key to human polymorphism .
- Some polymorphisms can be quite stable – so stable that they span the change from an ancestral to a descendant species.
