Answer 2

Answer:

Tasters” report that the strip tastes very bitter, while “nontasters” may only detect a small amount of bitterness, if at all. The ability to taste PTC is due changes in the TAS2R38 gene that affects the function of bitter taste receptors on the tongue.

The version of the gene that allows tasting of PTC is masked if it is paired with the version of the gene that does not allow tasting.  Traits could come from either parents. A person will only get a bitter taste from PTC if they inherit a copy of the gene for tasting PTC from both of their parents. Some people will have different genotype. so some people may have it Therefore in a family tree , only the grandfather and the youngest daughter can taste PTC.
