If genetics had no impact whatsoever then great apes would have the same intelligence potential as humans, as human races are more diverse then you give them credit for.
The impact of it's culture and behavioral like inbreeding being acceptable probably plays a bigger role though, but denying genetic impact is just putting your head in the sand because you cannot face reality not being equal. Which it ain't. It's also almost certainly a range, with most of the curves overlapping. If studied, I'd expect there to be a measurable impact in the rates of high intelligence individuals with the median intelligence being pretty close across all groups, but obliviously just my personal experience from interacting with people.
Race is a combination of genetic, and cultural factors such as nutrition, early childhood care practices, social values, etc.
Humans are far more genetically homogenous than many animal species due to a population collapse at one point in our developmental history.
Cultural practices can have a big effect on intellectual development, so disentangling any possible genetic factors from cultural ones can be very difficult, but there is very little evidence for genetic factors related to race also being related to intelligence at the population level. Obviously certain genetic disorders can have a significant effect.
