Question

The ability of certain people to taste the chemical called PTC (phenyl this carbide) is governed
by a dominant gene ‘T' and its inability to taste PTC by its recessive allele 't'. If 24% of
homozygous taster 40% are heterozygous tasters. Calculate the frequency of t’
1) 0.36
2) 0.56
3) 0.28
4) 0.42​

Answer 1

Answer:

The PTC Gene Soon after its discovery, geneticists determined that there is an inherited component that influences how we taste PTC. Today we know that the ability to taste PTC (or not) is conveyed by a single gene that codes for a taste receptor on the tongue. The PTC gene, TAS2R38, was discovered in 2003.
