Gene decides what smell you like

The craving for beer or cheese may have been set in the minds of people since birth.

Scientists have discovered the gene platform allows explaining why humans smell in a particular way after assessing the DNA of hundreds of individuals, according to a Nature report.

Richard Newcomb, a geneticist at the New Zealand Food and Plant Research Institute, said his team wanted to find out why some people were disgusted or attracted to specific smells.

Newcomb and colleagues examined nearly 200 people about their sensitivity to 10 different smells, which are common in food.

These smells, including malt, apple, blue cheese, purple flowers, are added to one of three glasses of wine in small quantities.

The odor content is gradually increased until the participants determine that the glass has added the smell.

After that, Newcomb took blood samples to test DNA and looked at different gene segments between people who could smell specific smells and others did not.

The difference between very large objects. For example, in the case of purple flowers, some people find it 10,000 times faster than the rest.
