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, 15 cannot taste the PTC. How many students would you expect to be homozygous dominant for the tasting gene? 1 mark
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 120 students, 3 cannot taste the PTC. Calculate the expected frequencies of the T allele in the student population. 1 mark
