A dominant allele, T, codes for the ability to taste the compound phenylthiocarb

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 125 students, 28 cannot taste the PTC. How many students would you expect to be heterozygous for the tasting gene?

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 125 students, 9 cannot taste the PTC. How many students would you expect to be homozygous dominant for the tasting gene?
