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

The taste of PTC is associated with a gene formed by the alleles responsible for tasting and non-tasting. These alleles are extremely important for us to be able to feel the different types of flavors.

The allele that codes for taste, is present in the taste buds of the tongue and can react with PTC molecules, allowing us to feel a characteristic bitter taste for that molecule. On the other hand, the non-gustatory allele is unable to react with PTC molecules. When these two alleles are combined within a genotype, the individual has a phenotype that allows sensitivity to the presence of the PTC flavor.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
