Scientists have claimed to find the reason behind why some people are better at performing some tasks while others are not. Experts say that family genes affect the working of brain. Genes of brain are responsible for the organizational ability, problem solving, and some mental illnesses of a person.

Researchers say that specific genes play a vital role in explaining differences in cognitive abilities, risk for mental illness and neurological diseases such as schizophrenia and Alzheimer's disease. This link established by researchers could help in developing gene-based therapies for these disorders.

Lead Author of the study, Dr. Alex Fornito from the Melbourne Neuropsychiatry Centre at the University of Melbourne, says that genes contribute towards the cases of mental illness and other brain disorders.

In order to study the effect of genes, researchers conducted a study on 38 identical and 26 non- identical twins. The results found that identical twins had the same genes whereas non-identical twins share only 50% of the genes.

Experts say that 60% of the differences between people related to the brain could be explained with the help of genes only.
