Begin with 1.0 x 105 wild type and 1.0 x 106 mutants.
This section has ignored the important evolutionary force of mutation. This series of problems builds models that consider mutation without reproduction. Suppose that 20% of wild-type bacteria transform into mutants and that 10% of mutants transform back into wild type ("revert"). In each case, find the following.
a. The number of wild type bacteria that mutate and the number of mutants that revert.
b. The number of wild-type bacteria and the number of mutants after mutation and reversion.
c. The total number of bacteria before and after mutation. Why is it the same?
d. The fraction of mutants before and after mutation.
