I hope I understood your question correctly:

Properties and methods can be inherited. Inheritance can be overwritten.

If you change the BackColor (?) of a form, it will not longer use the inherited value. The property will show in the property sheet in bold (you can "Reset to default" to restore inheritance).

If you change the BackColor - or any other property or method, for that matter - in a class, any forms (and classes) derived from that class will use the new value - except for forms where the inheritance is overwritten.

For methods, anything you write will break inheritance, but you can call the inherited method with DoDefault(), or with the scope resolution operator (::). You will hardly ever need the scope resolution operator, except in VFP3. DoDefault() (or scope resolution) allows you to run inherited method PLUS additional commands, or to run inherited method conditionally. (You need to take care both to pass parameters, and to return a value, if relevant.)
