What to put on Application

Okay, so for a university I plan on applying for, It has a section where you can put down if your parents/relatives work for the university. Both my father and my uncle do, but it has a seperate option on the application for someone who is not your parents but is still a relative. I would put this down, but I’m worried they will think that my uncle is my only relative who works there. I presume having a parent is better than an uncle? If so, should I just not put my uncle down? Both my parent and uncle have similar positions in the same department…

Is there an additional info section on the app? If so, I would put the uncle there. Certainly your parent should take the first space.
