### PTC Taste Sensitivity in Human Population Genetics

PTC (phenylthiocarbamide) taste sensitivity is a classic example of genetic variation in humans. The ability to taste PTC, a bitter compound, is determined by a specific gene known as TAS2R38, located on chromosome 7. This gene encodes a bitter taste receptor on the tongue, and its different alleles lead to variability in PTC tasting ability among individuals.

In the population, individuals are generally classified into two categories: "tasters" and "non-tasters." Tasters can detect the bitterness of PTC, while non-tasters cannot.
