They found a statistically significant genetic basis for four of the 10 fragrances: apples, violets, blue cheese and malt (maybe a craving for beer is hard-wired!). The genes responsible for detecting these scents were spread out across the genome, and it appeared that there was a single gene responsible for each of them.
