You identify with your real identity. Unless your genetic heritage has an actual, unmistakable impact on your life (e.g., being black, being clearly Native American, etc) it's no more relevant to who you are than your eye color. It might be nice to be a member of a distinct ethno-cultural group but nobody is entitled to it, and if your ethnic identity is so ambiguous that it's possible for you to be mistaken about it then it isn't all that relevant to your life. I can point to a genetic test and say "Here are my fractions from Irish, German, Native American" but pretending any of them represent a greater influence on my identity than "ambiguously-white American man" would make me a play-acting fool.
