Performance of a child in school depends on the gene -Study

Each child's ability to study is different, according to one study. In school, the child will be smarter or weaker depending on the gene. In the UK, over 1,000 pairs of children were researched to investigate the effects of the baby's gene composition and environment. The twins' children were selected in this research to see the genetic effect more effectively. Genes of identical looking children are about 5 percent identical. Even if twin babies don't look the same, up to 5 percent of the genes are identical.

In this study, school grades of children with similar genes and interest in the subject were found to be identical. Gene sequences of children were considered as the reason why the grade of the school was the same from primary to secondary. 5% of children's study contributions depend on DNA sequences. While 5% of the difference depends on the environment, different friends and teachers.

The twins' children's grades also differed in that children's storytelling and different environment were also responsible. The use of this polygenic score was predicted over 4,000 twins. This prediction was not a comparative study of twins. It only took into account differences in grades coming to school between two children. This polygenic score showed that the results of the study of children with the same gene are almost identical.
