1. A dominant allele, T, codes for the ability to taste the compound phenylthiocarbamide (PTC). People who are homozygous for the recessive allele, t, are unable to taste PTC. In a genetics class of 130 students, and 1 cannot taste the PTC. Calculate the expected frequencies of the T allele in the student population.

2. A dominant allele, T, codes for the ability to taste the compound phenylthiocarbamide (PTC). People who are homozygous for the recessive allele, t, are unable to taste PTC. In a genetics class of 155 students, and 44 cannot taste the PTC. Calculate the expected frequencies of the t allele in the student population

3.A dominant allele, T, codes for the ability to taste the compound phenylthiocarbamide (PTC). People who are homozygous for the recessive allele, t, are unable to taste PTC. In a genetics class of 125 students, 28 cannot taste the PTC. How many students would you expect to be heterozygous for the tasting gene? 

4. A dominant allele, T, codes for the ability to taste the compound phenylthiocarbamide (PTC). People who are homozygous for the recessive allele, t, are unable to taste PTC. In a genetics class of 125 students, 9 cannot taste the PTC. How many students would you expect to be homozygous dominant for the tasting gene?
