In recent years, genetic analyses, which show some tendency to this or that person of inherent nature, have become increasingly popular. For example, in China, parents do not send their children to sports clubs or creative circles, without conducting a similar study.
What genes are responsible for certain talents or passions? Latest studies show that what is in your genome, depends almost everything — sickness, and musical preferences, and even taste preferences.
Although scientists have managed to decipher the human genome (3 million elements that make up genetic material) from a final understanding of heredity modern science separate years of research. The fact that in the first place, the researchers seek to identify genes responsible for serious diseases – cancer, for example, or Parkinson’s disease. In the end, genes for ability in music or sport, are not a priority.
However, we can say that we are very much in the dark: today, learned some interesting facts about how genes determine certain characteristics. Today, genetic testing allows you to learn not only what people may be ill for life, but what medication fit for him, which food is better to avoid, what exercise will help lose weight…
And genetics can determine a predisposition to phobias. Researchers from the Medical center of Emory University in Atlanta found that the experience during the life becomes a parent – even before the time of conception, depends largely on what will be nervous system for future generations. In the experiment, laboratory mice were trained to fear the smell of cherry blossoms, feeding the electric current. In the end, the mouse fled as soon as there was this smell. But they are not limited to the reaction – they managed to convey the fear of the scent of wild cherry to their offspring by inheritance with the help of active gene DNA.
Genes determine our food preferences. “Most people have difficulty changing their dietary habits, even if they know that it is in their interest,” says Sylvia Berciano from the Autonomous University of Madrid, author of a study on the influence of genes on eating behavior.
The scientists examined the genome of more than 800 people and compared it with the results of the survey as to what kind of food they prefer. It turned out that genes have a significant impact on food choices and eating behavior. For example, passion for chocolate linked to gene oxytocin receptor, a gene, which is associated with obesity, affects the consumption of vegetables and foods high in fiber. Craving for fatty, sugary, love or dislike for salty foods – all this is because of the different variations of genes.
And even genetically predetermined to treat this disease belongs to the diseases with hereditary predisposition. According to the doctor-neurologist, candidate of medical Sciences Alexey Sergeeva, the presence of migraine in one parent suggests that the risk of migraine in a child – 60%. The probability increases to 90% if a migraine in both parents. Given that migraine is one of the most poorly diagnosed diseases, this information becomes even more important. Approximately 10% of the population in Russia suffer from migraines, with more than 8 million of them don’t know that it’s a migraine, and vainly trying to cope with the attack with the help of Advil or shpy. In fact, when a migraine will only drugs from the group of triptans. Understanding the risks associated with heredity, will help to be especially vigilant regarding the symptoms. Timely access to a neurologist and start treatment to avoid further trouble.
And finally, from genes to influence musical taste. Recently, a consumer electronics manufacturer conducted a major study: the experts studied the musical tastes of four thousand twins. The experiment was attended by representatives of different age groups. As a result, the researchers came to the conclusion that musical taste is largely predetermined by genes.
Most clearly display a predisposition to listening to classical music, pop music and hip-hop. This feature showed 53% of the participants. 46% of respondents had the inherent nature to love such styles as jazz and Blues. The attraction to more difficult areas such as rock and metal, was observed in 40%.
There is no dispute that education and the environment in which a child grows plays a key role in the formation of musical taste. As noted by the researchers themselves, with age, as you gain personal experience, the influence of genes on musical preferences gradually eroding.
