Biologist with a background in genetics here- there is no compelling evidence for statistically valid differences in measured intelligence on a racial genotypic basis. Most attempts to sort races by intelligence (e.g. The Bell Curve) end up being poorly designed junk science.
Dr. Adam Rutherford is a great pop science presence for debunking, or at the very least, addressing the claims that intelligence tracks with race on a genetic basis if you're truly interested in this topic.
