What about the “one drop” criterion for race? In the US, someone with 7 great-grandparents from Europe and 1 from Africa is quite often classified as black, not white. If the discrepancy is largely genetic, we should expect much more variance among black subjects (only African ancestors to very few African ancestors) than among white ones (very few to no African ancestors) - more than the width of the gap itself, actually. Is this what we observe?
What’s your alternative explanation for lower performance when reminded of a stereotype?
Why do I need to provide an explanation? It may very well be true that being reminded of a stereotype has a measurable effect on peoples’ performance.

Well you would need to quantify the amount of variation among both groups. American whites are pretty diverse too. Also, I would guess that blacks with mostly European blood are pretty unusual among American blacks. So I’m not sure what to expect.
So stereotype threat exists but only explains a smallish part of the gap, with most of the rest due to genetics? ’kay.
Quantifying diversity is hard: genetic variation I don’t know (KHAN!), specific genes even less, ancestry data isn’t available, samples like “famous people” are skewed, etc. I mostly meant “Barack Obama: a definitely white and a definitely black parent, and he’s black in the US race system. That seems common”.
But here’s a way to test: pick people with a race system in common (typically the US one, and I could do an European replication). Ask them to describe their race (ideally open-ended, but given small samples probably a set list). Take pictures of them and ask a (blinded, racially sampled) jury to guess their race. Measure some objective and hopefully relevant criterion like melanin in skin, or some cleverly chosen gene, or ancestry if you have it handy. Have them do some kind of intelligence test. Possibly split into groups and test conditions like “stereotype threat”.
The mostly-genetics hypothesis predicts that the objective criterion will be the best predictor, and the jury estimation will be a better predictor than the self-report because it looks at phenotypical evidence of genome rather than irrelevant things like native language. The mostly-culture hypothesis predicts that the self-report will be the best predictor, and that the results will vary widely depending on local race systems.
Clever stupid “it’s all interaction” idea of the day: What about a genetic predisposition to social cues such as stereotype threats?
What’s your alternative explanation for lower performance when reminded of a stereotype? Publication bias looks plausible.

I don’t know if it “exists” or not. But clearly if it does exist it does not satisfactorily explain the gap.
