1. In a pea plant population, the dominant allele for tallness (T) has a frequency of 0.04. What percent of the population would be expected to be heterozygous (Tt) for the height gene?
2. In a randomly mating population of mice, 13 out of every 100 mice born have white fur, a recessive trait. Calculate the frequency of the allele (G) in the population.
3. In a randomly mating population of mice, 11 out of every 100 mice born have white fur, a recessive trait. Calculate the frequency of the allele (g) in the population.
4. In a randomly mating population of mice, 2 out of every 100 mice born have white fur, a recessive trait. Calculate the homozygous recessive frequency for the population.
5. In a randomly mating population of mice, 12 out of every 100 mice born have white fur, a recessive trait. Calculate the homozygous dominant frequency of the population.
6. In a randomly mating population of mice, 11 out of every 100 mice born have white fur, a recessive trait. Calculate the heterozygous frequency for the population.
7. 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.
8. 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.
9. 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?
10. 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?
11. 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?
