selection coefficient
selection coefficient Symbol s or t. A measure of the sum of the forces acting to oppose the reproductive success of a particular organism, phenotype, or genotype. It varies between 0 and 1 and is related to fitness (W) by the equation: W = 1 – s. Hence, as the selection coefficient increases, fitness decreases.
