Intelligence has a 40-50% genetic basis

It's closer to 80% in adulthood

https://en.wikipedia.org/wiki/Heritability_of_IQ#Estimates

Various studies have found the heritability of IQ to be between 0.7 and 0.8 in adults and 0.45 in childhood in the United States.[18][24][25] It may seem reasonable to expect that genetic influences on traits like IQ should become less important as one gains experiences with age. However, that the opposite occurs is well documented. Heritability measures in infancy are as low as 0.2, around 0.4 in middle childhood, and as high as 0.8 in adulthood.

There's a ton of studies on HBD out there. IMO, we probably don't need more studies than we already have to support the concept of scientific race and important racial differences. But more is always better. You can find a lot more here
