in your own words, explain how a person may taste the bitterness of PTC by using the following vocabulary words in your explanation, trait, gene, genotype, phenotype, and alleles. 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.
