Final answer:
Selection is NOT one of the factors that influences calculated mutation rates in a population.
Step-by-step explanation:
The factors that influence calculated mutation rates are genetic drift, mutation rate, selection, and migration. However, out of these options, selection is NOT one of the factors that influences calculated mutation rates. Selection refers to the process by which certain traits or alleles are favored and become more prevalent in a population, but it does not directly affect the mutation rate.
