...de variety of different odors. The scientists then examined the fruit fly's 61 other odorant receptors and found that the proteins never made it to the ends of the olfactory neurons, called dendrites, where they would normally interact with the different incoming smells.

People with the PAV form of the hTAS2R38 gene were most sensitive to the bitter taste of PROP and PTC.
