April Flowers for redOrbit.com - Your Universe Online People react differently to the same smells. Something that smells wonderful to you could be offensive to your friend, but why this is so has been a mystery. The answer could lie in your genetic makeup, says a research team from Duke University. Their findings, published in the early online edition of Nature Neuroscience, reveal that a difference at the smallest level of DNA — one amino acid on one gene — determines whether or not...

Genes May Explain Why Some People Don't Like  Meat

If you don't like the taste of pork, the reason may be that your genes cause you to smell the meat more intensely, according to a new study. Duke University Medical Center scientists, working with colleagues in Norway, found that about 70 percent of people have two functional copies of a gene linked to an odor receptor that detects a compound in male mammals called androstenone, which is common in pork. People with one or no functional copies of the gene can tolerate the scent of...

Humans have the same receptors for detecting odors related to sex as do other apes and primates. But each species uses them in different ways, stemming from the way the genes for these receptors have evolved over time, according to Duke University researchers. Varying sensitivity to these sex-steroid odors may play a role in mate selection -- and perhaps prevent cross-species couplings, the researchers speculate. The researchers analyzed the sequences and functions of the gene for the odorant...
