Would you claim a nationality you were not dominant in, or deny it?

Imagine (seeing it would not fit you exact) you discovered through whatever DNA profile, that you were 37% Black, 20% Caucasian, 18% Hispanic, 13% Native American, and 12% Asian, if your appearance was more Caucasian or Italian (with most strangers assuming such) would you claim to be Caucasian or Italian if asked your nationality or race? If the Asian in you was noticeable would you say you were Amerasian (generic White plus Asian)? If none of the African American traits showed up in any obvious way, would you steer clear of claiming it seeing no one can tell or ask you of it? Would you determine as to what you would claim be predicated on something like seeking a job, joining a private club, applying for a grant, etc.?
