Answer:
False
Explanation:
Specialization is the top-down process of identifying lower-level, more specific entity subtypes from a higher-level entity supertype.
An entity supertype is a generic entity type that is related to one or more entity subtypes.
Entity supertypes and subtypes are organized in a specialization hierarchy.
Entity subtypes do inherit many of the relationships in which the supertype entity participates.
An entity supertype can have disjoint or overlapping entity subtypes.
