Is Tasting Ptc Dominant

PTC-tasting ability is a simple genetic trait governed by a pair of alleles, dominant T for tasting and recessive t for nontasting. … It has been suggested that PTC tasting may be related to the genetically determined level of dithiotyrosine in the saliva.

Is PTC tasting incomplete dominance?

Is the ability to taste PTC a genotype or phenotype?

The capability to taste phenylthiocarbamide (PTC) is a basic phenotype that has long been acknowledged to range in human populations.
