Document Summary
Natural selection - tendency for individuals with traits beneficial to survival and reproduction to pass those traits (alleles) on. Happens when there are differences among genotypes in their ability to survive and reproduce. This differential ability is usually referred to as fitness (ability to survive and reproduce) Another way to describe the role of selection is using the selection coefficient: Proportional reduction in fitness of a genotype with respect to the genotype with maximum fitness w = 1. The effect of selection on allele frequencies on allele frequencies will depend on. These can become new alleles in the population.
