Question about form fields disabled wilth JQuery

I have to create a form in which the first elements are two radio buttons. Depending on which one is selected, a few more fields will be available for the user, something like an extended version of the form, or they will disappear again like in the beginning. I'm doing this with JQuery of course.

So my question is: if I send the short version of the form, will I also send the fields which aren't available now whatever value they might have previously stored (or not)?
