Legacy question

If a parent did his/her medical residency at a college I am applying to (meaning mom/dad went to a different college, and a different Med school, but then did residency training (3-4 years) at university of X, to which I am now applying), how do I show that on the common app? When it asks iif I have any family that attended said institution, do I say yes because of this, or no, because the question is really referring to undergrad?

Call the admissions office and ask. Colleges differ on what they consider legacy
