How to make one radio button turn on another radio button

I am creating a form where activating a radio button in one place should activate a corresponding button elsewhere on the form. Specifically, if the user answers Yes with a radio button near the bottom of the form, a radio button in the header will indicate that they answered yes to this question. I know for text fields I can simply duplicate the field to repeat the same answer elsewhere, but I can't figure out how to do the same for a radio button.
