The gene responsible for the formation of intelligence, found on the X chromosome women. This is the conclusion drawn by researchers from the University of Glasgow.
According to the researchers, women have two X chromosomes, responsible for intelligence, and men only one. Guesses, scientists tested on laboratory rats.
As part of the experiment, the rodents introduced an extra dose of maternal genes. Due to the experimental increased size of the head and the brain, and wherein the body remains small. At the same time, the rats that received an extra dose of male genes have smaller heads and big bodies.
However, researchers have identified cells that had only maternal or paternal genes in 6 different brain regions of rats was monitored and various cognitive function - of power to the memory.
Assuming that this explanation works for the people of Glasgow researchers analyzed more than 12 thousand. Adolescents aged 14 to 22 years old. Scientists believe if you do not take into account the level of education, race, social status of the child, the best determinant of intelligence IQ was the mother.
