How to bind a property of inherited class from abstract class

I have an abstract class with some inherited classes:

public abstract class Base
{    
    public Base()
    {
    }
}

public class InheritedA : Base
{
    public bool PropertyA { get; set; }

    public InheritedA()
    {
    }
}

public class InheritedB : Base
{
    public bool PropertyB { get; set; }

    public InheritedB()
    {
    }
}

How can I bind in the XAML the PropertyA of inherited class when I just have a "Base" class referenced in the datacontext class:

public class DataContextHere: INotifyPropertyChanged
{
    public Base baseClass{ get; set; }
}

Something similar to this?:

<RadioButton IsChecked="{Binding baseClass.PropertyA}">

Edited Bonus: And, Is it possible to bind only if the boolean property exists and is true?

<RadioButton IsChecked="{Binding baseClass.PropertyA}">
<RadioButton IsChecked="{Binding baseClass.PropertyB}">

In this case, it is checked the first radiobutton if InheritedA is referenced in baseClass, or the second one if InheritedA is referenced.

Thank you

Like you do, provided that baseClass is a public property that actually returns an Inherited instance:

<RadioButton IsChecked="{Binding baseClass.PropertyA}">

public Base baseClass { get; } = new Inherited();
