   Oct 6, 2014 · Researchers have previously shown that a person's IQ is highly influenced by genetic factors, and have even identified certain genes that play a role. They've also shown that performance in school has genetic factors. But it's been unclear whether the same genes that influence IQ also influence grades and test scores.

   pmc.ncbi.nlm.nih.gov › articles › PMC4270739

   Intelligence is one of the most heritable behavioural traits. Here, we highlight five genetic findings that are special to intelligence differences and that have important implications for its genetic architecture and for gene-hunting expeditions. (i) The heritability of intelligence increases from about 20% in infancy to perhaps 80% in later ...

   Yet, although IQ differences between individuals have been shown to have a large hereditary component, it does not follow that between-group differences in average IQ have a genetic basis. [ 12 ] [ 13 ] [ 19 ] In fact, greater variation in IQ scores exists within each ethnic group than between them. [ 83 ]

   Are genetic differences associated with individual differences in intelligence test scores?

   • Twin and family studies report that genetic differences are associated with individual differences in intelligence test scores (Box 2). If studies from all ages are taken together, genetic differences account for about 50% (standard error [SE] about 2%) of the variation in intelligence .

   Are intelligence differences related to genetic variation?

   • The focus is on genetic variation and brain imaging-derived differences, including where those two sources overlap. For more than a century, the field of research that studies intelligence differences has had some controversies (Box 1). Notwithstanding these, research findings on intelligence have much consensus, based on robust findings.

   Jul 7, 2006 · THE GENETIC BASIS OF INTELLIGENCE. (August 2004) Intelligence is a very difficult concept to define. Intellect is described as “the power of the mind to think in a logical manner and acquire knowledge” [1]. Even psychology experts have not agreed upon what this actually means [2]. Intelligence can be divided into various subcategories such ...
