The study, researchers from the U.S. and Canada proves that just one mutation of the 16th chromosome is able to reduce the level of human intellect by 25%. As evidence, experts have analysed the genome of 700 volunteers and correlated mutations was found with the mental abilities of people.
Another interesting fact: the mutation of the 16th chromosome only reduces the intellect, but does not cause any problems with the psyche. Now, scientists are busy searching for mutations responsible for mental disorders, says JAMA.
The study's author, geneticist Sebastian Jackman, I am convinced that every mutation affects a living organism. Therefore, the human genome still remains a big mystery, and questions to the peculiarities of functioning of genes is much larger than clear-cut answers.
