Is intelligence inherited?

General intelligence definitely runs in the family. Twin studies (on both identical twins and fraternal twins) have found a heritability of IQ between 57% and 73%, and in some cases, even higher. Interestingly, genetic studies have revealed that a child’s IQ score is less affected by intelligence genes than an adults.

Who determines intelligence in a child?

children are more likely to inherit intelligence from their mothers because intelligence genes are located on the X chromosomes (and mothers have two). Mothers do tend to have two X chromosomes, but they aren’t identical chromosomes, and of course, they got one of them from their fathers.

Is IQ genetic or environmental?

Intelligence in the normal range is a polygenic trait, meaning that it is influenced by more than one gene, and in the case of intelligence at least 500 genes. Further, explaining the similarity in IQ of closely related persons requires careful study because environmental factors may be correlated with genetic factors.

Is IQ determined at birth?

Researchers found that the IQ of children adopted at birth bore little correlation with that of their adoptive parents, but strongly correlated with that of their biological parents. What’s more, this association became stronger as the children grew older.
