As a person whose favorite color is blue and lives in the town where wearing anything but blue in March is equivalent to asking for your friendships to end (Lexington KY), I thought I had to share this with you. Apparently, the mutation in OCA2 gene that resulted in blue eyes can be traced back to a single individual who lived around 10 centuries ago. But, the research also used mitochondrial DNA to determine inheritance patterns (it’s really hard to say anything conclusive with each generation that you go back when working with mtDNA). Still thought it was pretty Fancy. Go Blue!
This is an article that I read a while ago which described the effects of COMT gene and its function in clearing dopamine in the brain that is often released as a result of a stress response. There are two variants of the COMT gene: one which clears dopamine at a faster rate and another one which is a slower acting version. Usually, people with the slow variant do better on cognitive tests in the laboratory. However, under surges of stress, such as high-stake tests, when the brain is flooded with dopamine, researchers found that those with the slower variant were at a disadvantage. In Taiwanese national exams, students with the slow variant scored an average of 8 percents lower. “It was as if some of the A students and B students traded places at test time.”
What do you think about the influence of stress on your performance in school and other tests. Personally, I would love to know my COMT polymorphism in addition to ACTN gene. New genetics lab @ rafakoko?
