Living in a residential area of Cleveland dolaylarındaki 6 and 51 children ranging from ages 6 to 15 blood samples were collected. One group was calculated as the average IQ 136. Other groups, the average IQ was 103. All children were white. Separation of blood cells, the scientists looked at the children one by one chromosome number 6. One of the 37 genes on chromosome number 6 in different: the gene, called IGF2R IQ'lu group of high percentage of children seen in children than in normal IQ'lu two misliydi (16 per cent against 32 per cent). Research report published by the magazine in the May issue of Psychological Science in the shape of the IGF2R gene and on behalf of a gene called''5''allele was responsible for intelligence.
Plomin, however, this gene is remarkable that there is a''high''intelligence genes. This means that the gene is only an extra four IQ points. And in this gene is not enough to make a man gifted: The average IQ of this gene, while 23 percent of children with this gene has 54 percent of gifted children.
Insulinlike growth factor receptor-2 gene''Smart Insulin-like growth factor 2 receptor IGF2R-known by the name''. This gene is of great similarities with the insulin gene. Hormone in some cases, when an ordinary dock to a cell of the cell to commit suicide in some cases lead to cell growth. These two activities are normally followed during the development of the brain response. Insulin receptors in the brains of a mouse learning and memory regions covered by the National Health Institute, scientists realized that they concluded that insulin accelerates the growth of nerves.
This result supports the thesis that IGF2R'in brain and therefore affect intelligence, some geneticists kuşkulular for the accuracy of the results of the IQ-gene research. Plomin'in group of genes found in the academic aspects smart idea that a gene commonly found in children who are successful in claiming the group's spokesman at Johns Hopkins University Andrew Feinberg skeptical of ethnic differences in the gene they found''not originate Who knows?''He asks. On the other hand, Neil Risch of Stanford University said Plomin'in the opinions expressed in this research:''If I rastlantılara Plomin'in based on research. Find a gene on chromosome 37 by removing a gene from the gene it is wise not based on a scientific basis to claim that. For example, several studies of various personality traits such as schizophrenia, gene, genes involved in gene found curiosity. However, these studies did not achieve the same results repeated. This research zedeliyor credibility.''
Scientists to accept the claim that the IGF2R gene affects intelligence is not enough to solve the problem. Now we are being taken out a new question: how IGF2R affect intelligence? Intelligence is a very complex phenomenon that makes the problem even more complicated. An official from the National Health Institute,''a fact that healthy children perform better in school. Therefore, this gene may be considered to be effective, but if the child receives adequate food''he said. Cornell University psychologist Stephen Ceci of genes working in a vacuum,''said To answer this question before the need to clarify any further questions. Reveal how environmental conditions affected the genes that affect intelligence is a prerequisite. For example, the mother's diet during pregnancy can significantly affect even the intelligence''he says.
Plomin gene related to IQ in the meantime two more studied chromosome. To explain the results obtained from these plans in October. In the meantime, all the features to mental and physical DNA determines how a belief in the interaction with the environment in the finalization of the gene for the intelligent need to clarify that. In the meantime, the next two months, a physiologist in the IGF2R gene, a prenatal test and contribute to the designing work.
