WebDec 1, 1975 · DISCUSSION The stimuli Phenyl-thio-carbamide (PTC) is a toxic compound to a wide variety of animals. Its toxicity has been recently demonstrated in the flour beetle, T. castaneum (SOLIMAN, 1974). The adult beetles could sense the existence of this compound in their environment and avoid it. Increasing the percentage of PTC, from nil to 4% ... Web(a) Two small separated human populations A and B have respective frequencies of phenyl thio carbamide tasters (caused by a dominant) of 0.85 and 0.25. If 5 percent of population B comes from population A each generation, what will be the frequency of the tasting gene in population B after 1 and 10 generation? Previous question Next question

WebQuestion: Ability to taste the chemical phenyl-thio-carbamide (PTC) is inherited with a dominant allele (A) causing ability to taste and the corresponding recessive (a) causing inability to taste. With rare exception, human eye color is inherited as if a dominant allele (B) causes brown eyes and the corresponding recessive (b) causes blue eyes.

In 1931 Arthur Fox, a chemist at DuPont, in Wilmington, Delaware, synthesized phenylthiocarbamide (PTC). Some researchers reported a bitter taste when entering his laboratory, while others, including Fox himself, experienced no such sensation. Further study of this phenomenon by L.H. Snyder in 1931 led to the conclusion that the inability to taste PTC is a recessive trait. In 1932, Albert Blakeslee conducted a large-scale study involving the inheritance …
