Too strict upbringing affects DNA.

Children of strict parents may be prone to depression and suicide due to the fact that they have increased DNA methylation. These conclusions were reached by Belgian scientists during a study involving 44 boys and girls aged 12-16. The researchers divided the adolescent volunteers into two groups. The first included children of "soft" parents - supportive, giving significant freedom. Secondly, boys and girls who are often punished, brought up strictly and subjected to psychological manipulation. DNA samples were taken from all children and its methylation was analyzed at 450,000 sites. Methylation has been found in everyone - it occurs in every human body. But too many modified sites are often associated with the development of depression and increased suicidal tendencies. This is exactly what the scientists found.
