Friendliness is inherited

question of a person’s genetic predisposition to certain
social qualities. Richard Ebstein, a professor at the University,
together with a group of scientists determined the significant role of two genes in
This process is CD38 and CD157.

We all know people as sociable and closed.
Some like big companies, always happy to talk and have a lot of
connections in society. Others prefer solitude and indentation

Now Professor Ebstein told the scientific community about two
responsible genes.


About 1,500 young people were selected for the experiment.

The subjects completed three questionnaires that evaluated the social
adaptation, relationship to friendship, hostility, number of friends. Earlier these
questionnaires were actively used in cases of suspected autism
little children.

As a result, Singaporean scientists identified:

  • High expression (manifestation) of CD38 was expressed in greater
    number of friends and loved ones.
  • Low expression of CD38 manifested itself as an inability to
    in some cases, understand the hidden meaning with less
  • The various options in the structure of CD157 that were associated with
    autism were dependent on a person’s ability to
    active life in society.

Genetic effects on adaptation processes are associated
according to doctors, with the regulation of oxytocin by these genes. But Ebstein
did not disregard the fact that increased or decreased expression
CD38 and CD157 are detected in only 15% of people. The rest are
within average values. In the following stages, specialists from
University of Singapore plan to study the effect of genes on the course
