Answer Details
The ability to taste PTC (phenylthiocarbamide) is a heritable character, which means it is determined by your genes that you inherit from your parents. This means that if your parents have the ability to taste PTC, you are more likely to have that ability as well. The ability to taste PTC is caused by a specific gene called the TAS2R38 gene, which codes for a taste receptor that can detect the presence of PTC. Some people have a version of this gene that allows them to taste PTC, while others have a different version that does not. Therefore, whether or not you can taste PTC is determined by your genetic makeup, rather than by any acquired or morphological factors.
