Hair and eye color, growth, physique and nose shape are those visual signs in which we easily find similarities with parental. Alas, too, diseases can be hereditary. Most of the features associated with our genetics are physical. However, heredity can manifest itself in your personal preferences and way of life. Here are 10 amazing qualities for which you can thank your parents.
1. How kind you are
Your ability for kindness and empathy is determined by your DNA. A certain gene produces a receptor for oxytocin, a “love hormone”. It is available in three versions: G / G, A / G or A / A. G / G is maximum kindness and compassion. Option A / A is the minimum empathy, and A / G is the average. In the study, 348 people in 51.5% had a G / G variant, and 7.2% had type A / A.
2. Your interest in traveling
Some people lead a sedentary lifestyle, not venturing far away from their hometown. Others consider it a priority to see a maximum of terrestrial corners. The difference can be found in the variations of the dopamine receptor gene. A certain variation of this DRD4-7R gene is associated with curiosity and a desire to change places. Such people are distinguished by a thirst for wandering and certain adventurous. A total of about 20%.
3. Taste preferences
Some adore spices, other simplicity, taste of white rice. Food that is delicious for one person may be unpleasant for another. Favorite flavors, by the way, are also determined by genetics. The first discovery of the relationship between DNA and taste occurred in 1931. In the end, it was found that this is due to the TAS2R38 gene, which affects the taste buds. For example, variations of the TAS2R38 affect how much the child likes sweet.
4. Driving skills
The next time you are fined, blame your DNA. The neurotrophic factor of the brain (BDNF) is a protein secreted in the brain during certain activities. BDNF supports the optimal functioning of brain cells and supports memory and training. Some people have less of this protein, others have more, and this affects the mastery of new skills, the preservation of information and the ability to correct their actions as a result of mistakes.
5. Your popularity
If you have many friends, then you have inherited the “popularity gene” that makes people behave the way that others like it. For example, the popularity of men is associated with a gene that affects serotonin levels. A higher serotonin level leads to impulsivity, and such behavioral patterns make a young person very popular among peers.
6. Your musical talents
In order to become an outstanding musician, it will take years of practice and the right genes. Heredity affects both the presence of talent and the likelihood that a person will improve this talent with his own efforts. Those who lack “right” genes will achieve less than people who are gifted with musical abilities.
7. Your laziness
Some people go to the gym every morning, and others even move from the sofa to the fridge as an incredible exercise. You probably inherited your laziness, because our DNA determines how physically active we are.
8. Your love for coffee
In 2016, scientists discovered the PDSS2 gene that affects caffeine intake. A study of the population of Italy and the Netherlands showed the relationship between PDSS2 and the amount of coffee consumed by a person. People with a more active variation of this gene prefer coffee. Scientists believe that this is due to the fact that PDSS2 regulates the production of proteins that metabolize caffeine.
9. How much you have a heavy hangover
Recent studies have shown that DNA affects the potency, as well as the severity of a hangover. Some people have a gene mutation that affects how the body cope with alcohol. The body quickly processes it, but the process dramatically slows down immediately after alcohol turns into a toxic enzyme acetaldehyde, which causes a more painful hangover.
10. Who do you vote for
Your political views are also under the influence of genetics. The study of identical and heterozygous twins showed that the former were much more likely to have the same views than the latter. Thus, the predisposition to traditional or non-traditional values is laid down on the genetic level, and hence the sympathy for liberals or conservatives follows.
