The search for the intelligence gene was done by a study done on the genes of a group of high IQ children. There was a difference on the gene IGF2R on chromosome 6. Intelligence genes do not need environmental stimulation for them to work. In the chapter, Ridley discusses that there were studies done on separated twins which shows that there is heritability to intelligence and personality, and no correlation between IQ scores of adopted children living in the same family. Intelligence genes are also more expressive later in life because people start choosing their own environments and comfort zones so they have more ways to express themselves.
