WebUsing what you know about genetics, SNPs, and the PTC gene, explain why it is possible for a person to be a “weak taster.” The PTC gene has two alleles but that allows for 3 genotypes: TT, Tt, and tt. Those with TT can strongly taste the PTC and those with tt don't taste anything at all. This means that those with Tt will be able to taste ... WebCarte mondiale de la sensibilité des populations humaines au PTC Il est assez rapidement établi que la sensibilité au PTC dépend d’un gène à 2 allèles : un allèle dominant, qui confère la sensibilité, et un allèle récessif, associé au phénotype d’insensibilité.
