Question

Quizplus · Accepted Answer

The selection coefficient is a measure of the difference in relative fitness between one genotype and another. It is often denoted by s and ranges from 0 to 1, where a value of 0 means that the genotype has no disadvantage or advantage, and a value of 1 means that the genotype is lethal or completely sterile. The selection coefficient is a key parameter in population genetics because it determines how fast the frequency of a particular allele will change over time.
