9. Calculate the overall frequencies of light-coat mice and dark-coat mice caught on light-colored substrates. Show your work.
10. Calculate the overall frequencies of light-coat mice and dark-coat mice caught on dark-colored substrates. Show your work.
11. Using the Hardy-Weinberg equation and data from the table above, determine the frequency of the DD, Dd, and dd genotypes on the light-colored substrate.
12. Using the Hardy-Weinberg equation and data from the table above, determine the frequency of the DD, Dd, and dd genotypes on the dark-colored substrate.
13. Explain why it is necessary to collect coat color frequency data over a period of many years to determine whether coat color is an evolving trait.
