    If the items to be loaded in the dropdown list is static(like sex difference, Age, % Marks scored etc) , then we could use javascript to load the dropdownlist onclick/onchange/onchecked of radio button.

    If the items to be loaded in the dropdownlist is dynamic, (say the data comes from DB), we could use AJAX call backs to load the dropdown list on click of radio button.

    Hope this helps....

    Fetch all the results together in xml and parse itusing javascript.Your xml will contain all the possible combinations for radiobutton selections and corrosponding ddl.
    OR
    May be Ajax.
