Answer #1

The selection coefficient is denoted by s, and it is a measure of differences in fitness. The selection coefficient (s) of a given genotype as related to the fitness or adaptive value (W) of that genotype is defined as s = 1 – W. The value of a selection coefficient varies from zero to one. For example, If a particular genotype produces only 65 percent viable young, its selection coefficient will be: s = 1 - 0.65 = 0.35. So, the selection coefficient is used to calculate the rate at which allele frequencies change from generation to generation within a population.
