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.

<h3>What are dermal papillae used for?</h3>

The term "dermal papilla" can also be (DP). It is described as the hair follicle of an epithelial progenitor cell's chemical and physical niche. The dermal papilla's main job is to produce the hair shaft and rejuvenate the cycling section of the hair follicle. Dermal papillae are important because they reinforce the bond between the dermis and epidermis and reduce friction-related damage in places that are often used. Moreover, The dermis has a rough appearance thanks to the papillae, which interlocks with the epidermis above it to reinforce the bond between the two layers of skin. The papillae produce epidermal ridges on the palms and soles. These epidermal ridges give rise to fingerprints.
