Detailed explanation-1: -Explanation: Heritability or genetic influence on intelligence variation among group members is estimated to be approximately 50 to 80 percent. Certain scientists have suggested that this influence of genes becomes stronger in adulthood then it was in childhood.
Detailed explanation-2: -Heritability of intelligence refers to: the amount of group variation in intelligence that can be attributed to genetics. The most widely used modern intelligence test was developed by: David Wechsler.
Detailed explanation-3: -Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors.
Detailed explanation-4: -Conclusions From Genetic Studies In conclusion, twin studies show that individual differences in human intelligence can largely (50%–80%) be explained by genetic influences making intelligence one of the most heritable traits.
