如何使用原型框架在Javascript中实现OO？

Question

please give the example to me. I want a class, which is a abstract class name "Person" , and two abstract class named "Male" and "Female", which extends "Person", and two concrete class named "Young man" which extends "Male" and "Young woman" which extends "Female". Also, I need a multiple inherited class which called "Unknown", and it extends both "Male" and "Female"... ...

Thx in advance... (Using the Javascript prototype framework is allowed.)
