Genetics to a certain extent determines all spheres of human life. Alcoholism and drug addiction is no exception. It is worth to note that 100% of the genes depends only the sex of the baby and genetic diseases. In other cases, genes are allocated a certain percentage of influence.
In recent genetics research has studied the RNA sequence and identified genes that determine susceptibility to alcoholism, according to Science World Report. The researchers compared the genes of people suffering from alcoholism, and the genes of people without the disease.
Was discovered a whole network of genes, which in healthy people in the genome is not present. Probably this feature to some extent increases the tendency of a person to drink alcohol. For a clear definition of the role of genes in the formation of alcohol dependence requires further investigation.
