So, I was thinking about OOP and inheritance, and I got to thinking about a new construct in OOP where you specify dominant and recessive properties/methods like with real inheritance.

Consider two objects Mother, Father in a fictional language:

class Mother
{
    dominant void doWork()
    {

    }

    void beMotherly()
    {

    }
}

class Father
{
    void doWork()
    {

    }

    void beFatherly()
    {

    }
}

Then, you could create a new object that doesn't have a particular type itself, but is instead a juxtaposition of both provided types upon construction.

Child child = new (Father, Mother);
child.doWork(); // calls mother's doWork();
child.beMotherly();
child.beFatherly();

I think this could be interesting if developed further.
