As Michel indicated, living individuals must enter their own DNA test info here at WikiTree, if they'd like it shared here. You can help your mother join (at least as Family Member), if she so desires (add her email address to her profile and invite her). Then she can enter her DNA test info.
It appears that your father is deceased. If he took a DNA test, and if you manage his DNA test results, as manager of his profile, you can enter his DNA test info on his profile. On his profile, use the drop-down menu for his WikiTree ID and choose the DNA option (<== or click here). Then select the DNA Tests tab (<== or click here). There will be a yellow box warning you that you're entering someone else's DNA (which you can ignore, since that's what you want to do). There you can enter your father's DNA test info (be sure to click the "Add Test" button after selecting the particular DNA test and entering the info, to save it all).
