1. You have sampled a population in which you know that the percentage of the homozygous recessive genotype (aa) is 16%. Using that 16%, calculate the following: A. The frequency of the "aa" genotype. B. The frequency of the "a" allele. C. The frequency of the "A" allele. %3D D. The frequencies of the genotypes "AA" and "Aa." E. The frequencies of the two possible phenotypes if "A" is completely dominant over "a. 2. Among Death Valley mice, the dark allele (D) is dominant over the light allele (d). During a recent student field trip, the following mice were captured: Using the Hardy-Weinberg formula, calculate the following. A. The frequency of mice that express the recessive trait and are therefore homozygous recessive (dd). This is the q? value. B. The frequency of recessive alleles (d) in the population. This is the q value. C. The frequency of dominant alleles (D) in the population. This is the p value. D. The percentage of mice that are homozygous dominant (DD). This is the p? value. E. The percentage of mice in the population that are heterozygous (Dd). This is 2pq. F. Suggest a reason for the number of d alleles in the population.

2. Among Death Valley mice, the dark allele (D) is dominant over the light allele (d). During
a recent student field trip, the following mice were captured:
Using the Hardy-Weinberg formula, calculate the following.
A. The frequency of mice that express the recessive trait and are therefore
homozygous recessive (dd). This is the q? value.
B. The frequency of recessive alleles (d) in the population. This is the q value.
C. The frequency of dominant alleles (D) in the population. This is the p value.
D. The percentage of mice that are homozygous dominant (DD). This is the p? value.
E. The percentage of mice in the population that are heterozygous (Dd). This is 2pq.
F. Suggest a reason for the number of d alleles in the population.
