Technology channels () message: recently, scientists through the world's a genetic isolation of thousands of places to study, found that gene on our health and our personality profile than the modeling of a greater role.
According to this study shows that a person's height, weight, and all the features of profile, approximately 51% of the genetic characterization; cardiovascular function 25%; some features such as glucose and blood plasma cholesterol concentration, representing approximately 40%. But many documented personality characteristics such as nervous, export-oriented, open and committed only about 19% of genetic characteristics.
This research paper's authors have just Carlo-abecassis said: "my personal opinion is that we have evolved into a complex personality, relative to other features, personality more than other human characteristics is not deterministic. My point is the gene and environmental impact of the personality is smaller than the random factors. ”
As a United States statistical genetics at the University of Michigan Center for a scientist, abecassis and colleagues from the northeast (Italy in an island in the Eastern Mediterranean) 6,148. On the island, many residents are isolated. In these tests, about 95 percent of grandparents are Sardinia-people, including 5000 on brothers and sisters.
Researchers believe that their research is published by far the largest of a gene and characteristics of the thesis. Scientists test samples are extracted blood for medical examination and ask them to fill out a standard of personality questionnaires, but also for the liver and thyroid function, electrolyte concentration, cholesterol, glucose and other projects.
By calculated every feature under the influence of genetics, researchers first calculates a relative of each pair is shared between DNA quantity. For example, a pair of identical twins of almost the same DNA, brothers and sisters of DNA average half of the DNA is the same, aunt and nephew shuzhi or usually only 25% of the same DNA, church or cousins only some of the same DNA. 12.5
After that, the researchers will this information and health, weight, character and is compared to other data. Computer models to these characteristics and kinship, look at the whole research groups, each feature is subject to the influence of genes.
The study found that gene usually determines the person is fat or thin, but researchers said, regarding the weight issues, we cannot simply accusing us of genes. Engaged in the study of the United States National Aging Institute of deep-scientist David-piacere Singh said, "the way of life led to the prevalence of contemporary obesity. Of course, some individuals have a genetic advantage, you can have other people more resistant to modern diet and lifestyle adverse impact. ”
Interactive ask all data indicate that personality and blood and heart health is clearly no. For example, angry man does more than modest people more committed heart problems.
United States Maine's Jackson Laboratory senior scientist Wayne-Frank, said: "this study unusual, its size and a large number of features of a comprehensive analysis of unusual information. Importantly, and hereditary characteristics are related, you can improve future gene identification test capabilities. ”
Abecassis and his colleagues next want to identify with each of the features of the particular gene.
