Final answer:
The 'genius genes' likely have a role in determining intelligence levels, influenced by both genetics and environment. Genetics is said to control intelligence substantially, whereas the environment contributes to activating cognitive abilities. Traits signaling genetic fitness, per the good genes hypothesis, may also be related to intelligence.
Step-by-step explanation:
The concept of "genius genes" is related to the gene theory, which suggests that genes are fundamental in determining the characteristics of living organisms. One theory about what these genes do proposes that genes contribute to the component to intelligence. A study by Bartels, Rietveld, Van Baal, and Boomsma (2002) suggests that genetics control the level of intelligence to a large extent, but environmental factors also play a significant role by providing stability and change to trigger the manifestation of cognitive abilities.
The good genes hypothesis of sexual selection illustrates that beyond physical characteristics, genetic factors can also influence behaviors, which include the development of traits that signal an individual's genetic fitness. These traits, or ornaments, such as efficient metabolism or the ability to fight disease, are not only indicators of good health but also of superior genetics, which individuals may pass down to their offspring, potentially affecting intelligence and other cognitive abilities.
