QUESTIONS FOR LECTURE 2 1. What are the two coat-color variants in the Rock Pocket Mouse population in Arizona, and how is each variant adapted to its particular environment? 2. How many genes control the differences in coat color between the two Rock Pocket Mouse morphs? How many alleles? Which allele is dominant and which is recessive? 3. How does the Rock Pocket Mouse example illustrate that random processes of mutation are sufficient to produce advantageous variation over short periods of geological time (use mutation rate, reproduction rate, and generation time estimates in your answer)? 4. With a reproductive rate of 5 offspring per year per female, a population size of 5000 females, two copies of the MC1R gene in each individual, a mutation rate of 2 mutations that could produce a shift to black coat color, how many black-coat mutants will be born every 1000 years from a population that is all tan-coated? (You must be able to calculate this by hand). 5.
