>it has been observed that American blacks and Caribbeans have lower levels achievement than their African immigrant counterparts
>Despite American blacks being 15% European on average
>30% of American black males have a northwestern Euro Y chromosome
Would it be possible that the European DNA in American blacks actually made them less intelligent? DNA doesn't have a linear effect, hypothetically when a black would have >50% Euro DNA they become more intelligent, but <50% Euro DNA actually makes them less intelligent. Same thing with the Y chromosome, if a black male has over 90% African DNA with a European Y chromosome weird things happen.
For instance top NBA players look like they probably have around 10-15% white DNA, probably more, and many of them can grow beards, which is pretty much impossible for full Africans. The best NBA players wouldn't be 100% African or European, but like 20%-80% Euro-African, and Stephen Curry's like 60% white. Mike Tyson looks probably about 30% white. A similar thing probably happened with white DNA and intelligence, take a full African and they're intelligent enough to get by, add 15% Euro and they become dumber, add another 50% Euro and they start to become more intelligent than a full African.
