Webbselection on standing variation. In this model, a neutral allele arises and drifts in the population, then at frequency f becomes beneficial, and eventually reaches fixation. Depending on the value of f, this scenario can lead to a large variance in allele frequency spectra and in levels of linkage disequilibrium at linked, neutral sites. WebbGenetic variation is the difference in DNA among individuals or the differences between populations. The multiple sources of genetic variation include mutation and genetic …
