Scientists described 9 peculiarities that are transmitted genetically

“The smile of mom, but the character of dad”, most of us have heard these expressions many times, but do not say phrases like “I have the agoraphobia of my grandfather.” Meanwhile, the DNA stores a lot more information than we think. And although scientists still can not give an exact answer of what it is that most influences the character of the human being: genetics, environment or education, many researchers show that we not only inherit the physical aspect, but also, for example, “memories” in the form of phobias.

The team is Great.a guru figured out how to “memory of ancestors” can influence our personality thanks to DNA. Look what peculiarities is not very obvious you have inherited from your great-grandparents.

1. Phobias

Really, the memories can be transmitted across generations, but not in the way that we typically think of. This is confirmed by an investigation during which they trained mice to avoid the scent that resembles the aroma of the cherry blossoms. This influenced the DNA of the mice in which it was experienced: a part of DNA, which is responsible for sensitivity to odors, are made more sensitive in the semen of male mice.

In total, the children of these mice, and the descendants of these children are very sensitive to the scent of the cherry tree and tried to avoid it, even though you did not have determined reasons. The experiment showed that the event of the trauma may influence the DNA and, as a consequence, the behavior of subsequent generations.

Scientists believe that the results of the research are very important for the study of phobias, anxiety and post-traumatic stress disorder.

Thinks: perhaps your fear of spiders is not as irrational as it seems?

2. Extroversion

Some of the traits of character acquired not only during ripening, but thanks to DNA. For example, variants of genes WSCD2 and PCDH15 are associated with extroversion. Possibly, you’re as communicative as because you inherited it from your ancestors, and not because your mother signed up in a lot of disciplines in childhood.

In addition, there is a correlation between extroversion and the syndrome of hyperactivity and attention deficit.

3. Sense of humor

Some believe that the sense of humor is a trait acquired only dependent on the environment in which has grown the human being. But, anyway, during an investigation it was discovered that people with the allele of gene 5-HTTLPR often show positive reactions, including laughter and smiles. The participants in the experiment with a short allele often they smiled and laughed more sincerely than the people with an allele in the same gene.

The results of the research were confirmed even taking into account different ages, sexes, ethnicity and symptoms of depression.

4. Sensitivity to stress

Some people are more prone to stress, and this peculiarity also can be transmitted from parents to children. The specialists claim that, if the mother feels stress during the pregnancy period, your child may be more prone to stress.

In addition, there is even a risk when the parents are under the influence of the stress before you decide to have a child: chronic stress causes damage to the chromosomes.

However, it’s not worth going into a panic: the changes to the DNA stress-related, may be reversible to some extent with the help of cognitive behavioral therapy and mindfulness meditation.

5. In excess of the vices

The genetic influences on a 40-60 per cent in the risk of developing dependence to the vices. In particular it was studied in detail the connection between this dependence and the gene for the D2 subtype of the dopamine receptor. Probably, people with a deficiency of genetically determined of the dopamine D2 receptor are more prone to the consumption of substances that cause addiction, since they are less susceptible to the influence of the natural dopamine.

6. The ability to sleep well in a small amount of hours

Some people get enough sleep at least 5 hours, at the same time retaining the ability to function in a normal way. This is the variant of the gene p. Tyr362His, also called the gene of Thatcher, as the first minister slept 4 hours a day and it felt perfect. Persons with this peculiarity not only sleep less, but also perform a much better task of mental activity even after 38 hours of being awake.

By the way, not only Thatcher could boast of this ability. The inventor Thomas Edison also slept less than 5 hours.

7. Tendency to save

When it comes to money, our actions on a third party are explained with natural factors, according to experts. This showed a research published in the Journal of Political Economy. It was found out that some people are genetically more prone to save, regardless of income level, sex, and education.

In addition, people are “genetically” savers tend to have an easier to abstain from the vices, for example, they are less prone to obesity or smoking. This happens thanks to the permanence in their behavior and self-control, which must be your DNA.

8. Musicality

Genetics can play a large role, much larger than the practice, when it comes to musical talent, in particular, the recognition of tone and rhythm. The research of identical twins and fraternal compared the ability of people who were dedicated to the music and singing. It turns out that some people, who practiced the least, even so, demonstrated better results than those who are engaged for a longer time.

One of the twins had even practiced 20 228 hours more than his brother, but could not overcome it in their musical abilities. The scientists explain that some aspects of musical talent are based in the genes.

As you can see, we received from our ancestors more than we thought. What interesting features you inherited from your parents?
