Question

Now that we have practiced using the Hardy-Weinberg equilibrium equation, let’s apply it to real field data collected on rock pocket mice. In this data, we will compare the gene pools of populations of pocket mice caught on light colored surfaces vs dark colored surfaces to show how environmental selection effects the gene pool. The data collected is summarized in the table below: Environment Light Colored Surface Dark Colored Surface Mice with light-colored fur 120 3 Mice with dark-colored fur 48 54 Total number of mice caught 168 57 Calculate the overall frequencies of light-colored mice and dark-colored mice caught on dark-colored substrates. Remember that light fur is recessive and dark fur is dominant. The frequency of light-colored mice is equal to The allele frequency of dark-colored mice is equal to Calculate the allele frequencies of p and q in the populations of mice caught on light-colored surfaces. p is equal to q is equal to Hardy-Weinberg Equation: p2+2pq+q2=1 Using the Hardy-Weinberg equation and data from the table above, determine the frequency of mice with the homozygous dominant, heterozygous, and homozygous recessive genotypes on the dark, rocky lava substrate. The frequency of the homozygous dominant genotype is The frequency of the heterozygous genotype is *The frequency of the homozygous recessive genotype is
