Question

Assume the absolute fitnesses of three genotypes, A1A1, A1A2, and A2A2 are 5, 5, and 3, respectively. A. What are the values of relative fitness, if we normalize the genotype with greatest fitness to have relative fitness equal to 1? A1A1 A1A2 A2A2 B. The selection coefficient (s) is a measure of the relative strength of selection acting against a genotype. What is the value of the coefficient of selection for the A2A2 in this example? C. Based on the information provided, which allele is more likely to become fixed in this population?
