Research published in the American Journal of Medical Genetics found a strange relationship between eye color and the risk of suffering from alcoholism.
Their analyzes found that people with light eyes (blue, green and light brown) would be at greater risk of suffering from alcoholism compared to people with dark eyes.
People with light eyes would be more at risk of suffering from alcoholism
The sample was composed of 1263 adults of European-American tendency and a stratified control group. The variables of age, sex and genetic ancestry were controlled.
The authors explain that the relationship between eye color and the tendency to alcoholism is found in the set of genes that encode both characteristics. Specifically, they found that the imbalance between alcohol dependence is related to the GABRB3/GABRG3 gene receptor and the eye color genes OCA2/HERC2.
According to the researchers, these data could be useful in the future to develop accurate diagnoses of alcohol dependence.

Research like this allows us to understand the intricate process of coding our phenotypic characteristics and our behavioral tendencies. However, we must not forget that genetics influences who we are but determines us. The environment in which we are exposed plays a fundamental role in the development of our behaviors and we cannot leave that aside. Furthermore, there is also a lack of more data to verify this relationship. So, if you have light eye color eyes, you can rest assured.
