Yes, the ability to taste PTC paper is determined by a dominant gene. If an individual inherits the dominant allele for tasting PTC, they will be able to taste it. If they inherit two recessive alleles, they will not be able to taste it.
In studies comparing the percentage of tasters versus non-tasters for PTC and thiourea, it is typically observed that the genetic basis for tasting these compounds is similar, with the same individuals often categorized as tasters or non-tasters for both substances. Generally, a higher percentage of the population are PTC tasters compared to thiourea tasters, as PTC tasting is a more widely studied genetic trait. This variation arises because PTC tasting is linked to a dominant allele, while the ability to taste thiourea may involve different genetic factors. Overall, while the same individuals are assessed for both, the proportions of tasters can differ significantly.
Yes, two people who cannot taste PTC (phenylthiocarbamide) can have children who can taste it. This is because the ability to taste PTC is a genetic trait influenced by a dominant allele. If both parents are homozygous recessive for the PTC tasting gene (tt), they will not be able to taste it, but if they carry a recessive allele (t) and a dominant one (T), there's a possibility of passing the dominant allele to their children, resulting in offspring who can taste PTC.
As of July 2014, the market cap for PTC Inc. (PTC) is $4,464,804,555.68.
The symbol for PTC Inc. in NASDAQ is: PTC.
Pre -Trial Conference.
PTC Alliance was created in 1924.
Yes, it is possible for two parents who can taste PTC to have a child who cannot taste PTC. PTC taste sensitivity is determined by genetics, and it is possible for genetic variations to result in a child with different taste abilities than their parents.
99.9% of PTC sites are absolutely scam.
PTC Punjabi - Canada - was created in 2011.
"PTC" is the standard abbreviation for Positive Temp. Coefficient Fuse. They are often resetable.
The ability to taste PTC (phenylthiocarbamide) is inherited in a Mendelian manner, primarily influenced by a single gene with two alleles: one for tasting (T) and one for non-tasting (t). Evidence supporting this inheritance includes family studies showing a pattern of dominant inheritance, where tasters have a higher likelihood of having tasters in their offspring. Additionally, population studies reveal varying frequencies of tasters and non-tasters across different ethnic groups, consistent with genetic variation. Finally, molecular genetic studies have identified specific mutations in the TAS2R38 gene associated with the ability to taste PTC, providing direct genetic evidence of inheritance.
