Question

Quizplus · Accepted Answer

The fact that intelligence is determined by many genes, each contributing less than 1 percent of the variation, indicates that intelligence is a polygenetic trait. This means that there are multiple genes involved in determining intelligence, and each gene has a small effect on the overall level of intelligence. This also means that intelligence is heritable, but the inheritance pattern is complex and not determined by one or a few dominant genes. Intelligence can also change across the life span, and there is evidence that beliefs about intelligence, such as a growth mindset, can influence intellectual development.
