Which of the following statements about phenylthiocarbamide (PTC) is not correct?
Answer Details
The statement "Ability to taste the chemical is hot inheritable" is not correct.
Phenylthiocarbamide (PTC) is a chemical compound that some people perceive as intensely bitter, while others do not taste it at all. The ability to taste PTC is determined by genetics, and the trait for PTC tasting is inherited. However, it is not a dominant trait, meaning that someone may inherit the gene for tasting PTC from one parent, but not be able to taste it because they also inherited a non-tasting gene from the other parent.
Therefore, the correct statement is that the ability to taste the chemical is inheritable, but it is not a dominant trait, so some people may not be able to taste it even if they inherit the gene for tasting it.
