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 160 students, and 40 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 105 students, and 45 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, 10 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, 18 cannot taste the PTC. How many students would you expect to be homozygous dominant for the tasting gene?
5. 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 {y} students, and {x} cannot taste the PTC. You have already calculated the heterozygous and homozygous dominant frequencies. How could you check your answers for for the heterozygous and homozygous dominant frequencies are correct?
6. A population is at genetic equilibrium if
A.there is no change in population numbers over time
B.small populations migrate slowly
C.superior breeding mates are selected
D.there is no change in allele frequencies over time
I greatly appreciate all this help. Its mandatory for me to understand and finish this course. THANK YOU EVERYONE
