Which of the following is an incorrect statement about the inheritance of the ability to taste the chemical PTC (phenylthiocarbamide)? The ability to taste PTC follows Mendelian patterns of inheritance. The non-taster phenotype is a recessive trait. Any child born of parents who are both able to taste PTC will inherit the ability to taste PTC. Two children of taster parents can inherit opposite PTC-tasting phenotypes. The inheritance pattern of PTC tasting differs from the inheritance pattern of hairline contour (widow's peak).
