The ability to taste PTC is due to a single dominant allele, T, which means both TT and Tt genotypes can taste PTC. In a population of 6800 students that attend a high school in the metro area you find that 3436 are homozygous dominant (TT), 2790 are heterozygotes and 574 cannot taste PTC (tt). What is the allele frequency T and t? Show your work.
