<p>I think it’s best to identify on applications in the same way one would self-identify if asked by an acquaintance what one’s ethnic identity is, whether that’s a single ethnicity or more than one. (And there’s always the option not to report ethnicity, as well.)</p>
<p>For example, I have a friend who, genetically speaking, is a multiracial – he has a white mother and a black/Asian/Native American father. He self-identifies as black, though, because that’s the community with which he feels most aligned.</p>
