What determines a person's smartness, or the level of education he or she receives? Is it their parents, or their deeds? The less expected answer to this question could be genes. A new research may have found out the possible answer to these questions.

In a unique genetic experiment, researchers have now found 74 genes in our body. These genes somewhat decide how far one gets education in school. This may also depend on which kind of gene a person has.

As indicated by the examination done by the Social Science Genetic Association Consortium, aside from social and natural elements, genetics variables are additionally connected with education. 

For this study, specialists broke down the genetic data from 300,000 individuals. These people were of European drop, who had taken an interest in past studies where their education had been recorded. 

Previous exploration in this field has demonstrated that genetic elements represent around 20 percent of variety in education accomplishment. 

The recently recognized genetic variables represent a little part of this variation, the analysts said. 

The extent of the study, distributed in the journa,l Nature, made it conceivable to answer questions not ready to be tended to yet.

For instance, the scientists could distinguish many more genetic components that seem to add to intellectual capacity than had been already known. 

The study has suggestions for future exploration, where these connections can be further investigated, and more impressive results can be derived. 

"These study results will enable us to ask more refined questions about the genetic and environmental underpinnings of educational attainment and their health consequences," said Jonathan King, program director in US National Institute on Ageing.

"For example, we've known for quite a while that education appears to be a protective factor against Alzheimer's," King noted.

"Perhaps ultimately, we'll be able to learn why and how educational attainment seems to be protective of cognition in later life," King said.
