Personality is formed both taking into account character traits inherited from parents, and in accordance with the environment. To this day, disputes continue about which of these factors plays a big role. Some are firmly convinced that with the help of proper upbringing, any congenital defects can be corrected, while others are confident that heredity always determines what personality will eventually form. In the article we will talk about what an important role in our habits & nbsp; and preferences played heredity.
How heredity influences the formation of personality

Driving a car
Driving – not such a difficult task – all you have to do is learn a certain amount of traffic rules and practice a bit. But still, some people can not cope with this task, despite the sincere desire to drive a car. One interesting study helped explain this phenomenon. It turns out that there is a special chain of genes that can directly affect memory, orientation in space and reaction speed. It turned out that 30% of the world's population is better off not even thinking about driving.

Predisposition to bad habits
Such addictions as alcoholism, drug addiction and smoking – not only social problems, but also medical ones. Genetic predisposition – decisive factor in the development of addictions. The likelihood that a person will become addicted to smoking is 70% dictated by genetic characteristics.

Laziness
As it turned out, there is even a genetic predisposition to laziness. The desire to do nothing all day long, except to lie in bed in front of the TV, is also due to a hereditary factor, scientists say.

Love to travel
There are 2 categories of people. The former cannot always stay in the same place, they are attracted by distant countries, and they cannot imagine their life without frequent trips to new places. Others are absolutely calm about traveling and feel quite comfortable if they are not expected in the near future. In fact, constantly pulling on the road is not due to excessive romanticism or passion for adventure books, the DRD4-7R gene is to blame, the presence of which is due to the tendency to change places. Only 20% of people are genetically predisposed to travel.
-
Musical tastes
Genetic predisposition is also a decisive factor in the choice of music. In 2009, Nokia conducted a large study, the main task of which was to find out what role heredity plays in shaping musical tastes.
As part of the experiment, scientists interviewed 4,000 pairs of twins. It turned out that the younger a person is, the more tangible influence genetics has on the formation of his musical preferences. However, as a person grows older, this dependence weakens more and more, and by about 50 years, the environment becomes the decisive factor.
-
Phobias
It is believed that phobias can develop only as a result of negative life experience, which leads to the appearance of an irrational fear of various phenomena or objects. This view was refuted by scientists from the Emory University School of Medicine, stating that phobias are passed down from generation to generation. Researchers instilled a fear of cherries in mice with electric shocks. The offspring of mice with an imposed phobia were also afraid of this berry.
-
Partner selection
It's rather sad, but even in love relationships genetic predisposition plays a major role. When a person chooses a permanent sexual partner, eye color, a beautiful figure or common interests are not at all the decisive factors in choosing. It's all about a family of genes called MHC (major histocompatibility complex). The results of numerous studies indicate that women tend to choose a partner with a MHC that will be as different as possible from their own. Thus, there are more chances for the conception of healthy offspring.
