Most children's intelligence is hereditary

Up to 40% of children's intelligence is inherited from parents, according to a new study.

The findings from the largest gene study ever for children's intelligence have fueled a long debate about whether intelligence is a natural product or nurturing process.

New research confirms, intelligence is a genetic product.

Using genetic data and IQ test results from thousands of children in four countries around the world, researchers at the University of Queensland (Australia) have sought to isolate the environmental impact factors. .

They found that 20% - 40% of the variation in children's IQ was due to genetic factors, lower than the results of some previous studies (40% - 50%).

Dr. Beben Benyamin, a member of the research team, said: 'Our estimates from DNA information are lower than studies for families, but it is still consistent with the conclusion that children's intelligence is due to heredity '.

The results showed that many genes can contribute to children's intelligence. Specifically, each gene has a small contribution but a total of cumulative effects.

According to Professor Benyamin, mastering the factors affecting intelligence is extremely important, because IQ is a good sign to help predict a person's life expectancy, academic achievement and income. Benyamin added that the findings could also help researchers better understand intellectual disabilities.
