... the evolu- tion of gene frequencies that allows for the effects of mutation, random drift, selection, recombination, population subdivision and so on, one can ask ques- tions like ‘How long does ... variation. Understanding how genotypic variation translates into phenotypic variation, and how it is structured in populations, is funda- mental to our understanding of evolution. Understandin...
