The genetics of intelligence: twin and adoption studies.

Genes may influence intelligence indirectly could play a different role in different environments. A technique that examines how specific genes interact with the environment to influence behaviours, including those related to intelligence. Can be predicted to some extent by the collection of genes that individuals inherit pool together to influence general cognitive ability. Gene knockout (ko) studies: involves removing a specific gene and comparing the characteristics of animals with and without that gene: found certain genes do effect intelligence. The opposite adding a gene animal receiving this gene is called transgenic animal. Doogie mice manipulated nr2b gene encodes the nmda having more = retains more information. Rosenzweig and diamond study enriched environment bigger brain and more synapses can make more association.
