How much does genetic difference affect education level, occupational status, and income?
Many studies have shown that the environment in which a person spends his childhood has a

It has been confirmed that the socio-economic environment brought about by parents has a great impact on the lives of children, but on the other hand, the 'genes' that are passed down from parents to children affect the educational level, occupational status, and income of children. It is not clear if it is affecting it. Therefore, a research team led by Professor Jani Erola of the University of Turku in Finland, based on survey data of 6529 pairs of twins born between 1975 and 1986, 'educational level, occupational status, income We analyzed how the differences are related to the genetic differences and whether the genetic effects depend on the socioeconomic status of the parent.
The data analyzed included the level of education of the twins up to the age of 28, their professional status at the age of 30, and their income at the age of 32 to 36. The research team also states that they used ANOVA to consider the interaction between genes and the environment.
As a result of the analysis, there are five major findings. The first is that the genetic influence of education level, occupational status, and income was most pronounced at 'education level,' while the least impact was at 'income.'
As a second finding, the research team said, 'In the group classified as'socio-economically most advantageous'among the research subjects, the genetic influence was strong in all items.' I have listed it.
The third finding is that 'whether genetic differences affect a child's life depends on'how old the child was when the parent was in a socio-economic advantage.'' The wealth of parents in their very early childhood does not seem to have much of an impact on their children's future.
As with the third, the fourth finding is about 'timing', so 'parental socio-economic status' has the strongest influence on 'genetic differences' in terms of education level, occupation, and income. , It is an early 'education level' in chronological order. It is believed that 'professional status' depends on the 'educational level' before becoming a member of society. On the other hand, 'income', which seems to be related to education level and professional status, was not significantly affected.
Researchers are interested in the 'non-shared environment,' which is an environment other than the home, where the 'shared environment,' which is the relationship with parents in childhood, does not significantly affect the educational level, occupational status, and income of life. The influence of was great. ' Especially for children in economically advantageous families, the influence of the non-shared environment was strong.
The genetic background of social inequality is a lesser-studied part, but it is certain that children are influenced by many factors, including their homes, genes, and growing environment. Professor Erola believes that by considering the impact of genes on learning, it is possible to create new approaches to correct social inequality.
