Problem
One population has absolute fitness values of WAA = 0.7, WAa = 0.8, and Waa = 0.9. Another independent population has absolute fitness values of WAA = 0.85558, WAa = 0.97779, and Waa = 1.1. What are the genotype-specific relative fitness values in each population? What genotype(s) and allele will increase in frequency in each of the populations? How will the mean fitness (w) change over time in each population under natural selection? How will total population size (N) of each population change over time? What does this example illustrate about the difference between absolute fitness and relative fitness?
