Pls help i will mark you brainliest if you answer correctly i will give 30 points!!! In your own words, explain how a person may taste the bitterness of PTC by using the

following vocabulary words in your explanation (choose any order): trait, gene, genotype, phenotype, and alleles.

Underline each word as you use it in your explanation. In this explanation, you can treat PTC taste sensitivity as a single-

gene trait.

PTC gene has two main alleles; one that codes for tasting and the other non-tasting. The allele for tasting determines a trait of tongue papillae that can bind the PTC molecules. Non-tasting allele forms papillae that are unable to bind PTC effectively. Therefore, the combination of these alleles in the genotype of a person determines their phenotype – PTC sensitivity.

Individuals are often characterized as “tasters” or “non-tasters” of PTC, but there is some variability amongst tasters in how much bitterness they can detect. ... The ability to taste PTC is due changes in the TAS2R38 gene that affects the function of bitter taste receptors on the tongue therefore, the combination of these alleles in the genotype of a person determines their phenotype – PTC sensitivity.
