We do share a lot of genetic code, so checking for a specific aminoacid sequence could very unsurpisingly detect it in both

People have tried spoofing with dogs, but dogs aren't even that close genetically compared to other animals. Makes one wonder if they'd be able to detect a chimpanzee.

The real test should be sending in your own genes twice. They might not detect exactly the same because of minor mutagenic differentiation that has taken place (or because you're a chimera!), but they should easily place you into the same family tree as yourself.
