Scientists Explain the Genetics of Smell

September 25, 2013

We all smell different odors, that is according to the results of a study published in Current Biology journal. Based on the research article, genetics differences of individuals determine the ability to smell different odors.

About 200 individuals were tested for their sensitivity to different flavors. Then the researchers searched for areas of DNA that differed between those that could smell a given compound compared to those who could not. The study suggested that sensitivity to four of the compounds tested malt, apple, blue cheese and violet flowers is based on genetic differences. The differences in sensitivity did not seem to be linked to ethnic background.
