A big question that early geneticists attempted to answer is, what evolutionary forces might be affecting PTC taste variation. PTC is a fully synthetic substance and does not occur in nature. However, the perception of bitter taste may well have adaptive value as many plant toxins and medicinal active chemicals are bitter. In fact, chimps were found to have nearly the same frequency of taster vs. nontaster alleles as humans. In 1950, it was discovered that taste perception of I-5-vinyl-2-thio-oxazolidone, a toxic compound in cabbage that can cause goiters, corresponds exactly to PTC taste sensitivity. If the ability to taste PTC corresponds to the ability to taste certain naturally-occurring chemicals, then the PTC taster allele could have adaptive value. Do the population genetics data support this speculation? 6. Speculate on how selection might maintain the PTC alleles at their current frequencies.
