Chromosome 5
Environment
Ridley begins by exploring the world of genetics. He says that it is not just black and white as people may come to think of it but there are also many details in between that people are missing. Genetic inheritance is affected by many factors. These factors include the principles of pleiotropy, pluralism, and the environment. These all affect the individual significantly.
Chromosome 6
Intelligence
He also talks about a study done on the genes of children with high IQ numbers. They noticed that there was a difference in the gene IGF2R on the chromosome 6. He later discovered that the intelligence genes cannot be only considered by themselves, but also all the other factors that affect it like the environental stimulation that is required for it to function. Through other studies, Ridley noticed that there is heritability to intelligence and personality.
